Question # 1 Solution
Answer:
32≤x≤48 is the best estimate for the amount of money, x, that Erika has to pay to get to her destination. Hence, option D is correct.
Stepbystep Explanation:
Information Fetching and Solution Steps
 Erika estimates that she is 200 to 300 miles away from her destination
 Car travels 25 miles per gallon of gas
 Cost of each gallon being $4.00
As Erika estimates that she is 200 to 300 miles away from her destination, and car travels 25 miles per gallon of gas. So,
 First dividing 200 by 25 to get the number of gallons a car needed to make 200 miles
i.e 200/25 = 8 gallons.
As cost of each gallon being $4.00.
So, 8 × 4 = 32$ is the amount she needed to make 200 miles.
 Then dividing 300 by 25 to get the number of gallons a car needed to make 300 miles
i.e 300/25 = 12 gallons.
As cost of each gallon being $4.00.
So, 12 × 4 = 48$ is the amount she needed to make 300 miles.
From the above calculation, we observe that 32$ and 48$ is the best estimate between 200 miles and 300 miles.
Therefore, 32≤x≤48 is the best estimate for the amount of money, x, that Erika has to pay to get to her destination. Hence, option D is correct.
Question # 2 Solution
Answer:
Consultant B offers the cheapest price for a five hour session.
Hence, B. Consultant B is the correct option.
Stepbystep Explanation:
Analyzing the offer price of Consultant A, B and C for a Five hour session:
 Consultant A chargers $160 for the first hour
 $75 per hour after the first.
So, for five hour session, Consultant A is offering the price:
$160 + $75 + $75 + $75 + $75 = $460
 Consultant B chargers a flat rate of $90 per hour
So, for five hour session, Consultant B is offering the price:
$90 + $90 + $90 + $90 + $90 = 450 US$
 Consultant C chargers $140 for the first hour
 $80 per hour after the first.
So, for five hour session, Consultant C is offering the price:
$140 + $80 + $80 + $80 + $80 = $460
Comparing the price offers of Consultant A, B and C
So, by comparing the price offers of Consultant A, B and C, we determine that:
 Consultant A is offering the price $460 for five hour session.
 Consultant B is offering the price $450 for five hour session.
 Consultant C is offering the price $460 for five hour session.
So, from this comparison, we conclude that Consultant B offers the cheapest price for a five hour session.
Hence, B. Consultant B is the correct option.
Question # 3 Solution
Answer:
They spent 4 nights at the hotel. Hence, option B is correct.
Stepbystep Explanation:
To determine:
how many nights did they stay at the hotel?
Information Fetching and Solution Steps
 A hotel chargers $225 per night to rent a suite.
 The hotel also charges $75 per day for full room service.
 Jessica and Ashely purchased full room service for every night.
 They stayed at the hotel and spent a total of $1,200
As the total amount they spent = $1,200
As $75 is the service charges as Jessica and Ashely purchased full room service for every night.
Per night charges = hotel chargers + service charges
Per night charges = $225 + $75 ⇒ $300
So, total nights will be calculated as:
Total nights = total amount they spent ÷ Per night charges
Total nights = $1,200 ÷ $300 ⇒ 4 nights
Therefore, they spent 4 nights at the hotel. Hence, option B is correct.
Question # 4 Solution
Answer:
Hence, h − 57.5 ≤ 7.5 is the absolute values which best represents this restriction, where ( h ) represents height. Hence, option A is correct.
Information Fetching and Solution Steps
 A certain ride at an amusement park requires that children be at least 50 inches tall but no more that 65 inches tall.
Let us take the equation of following absolute value:
h − 57.5 ≤ 7.5
We know h − 57.5 ≤ and h − 57.5 ≥ −50
h − 57.5 ≤ 7.5 (Condition 1)
h − 57.5 + 57.5 ≤ 7.5 + 57.5 (Add 57.5 to both sides)
h ≤ 65
h − 57.5 ≥ −7.5 (Condition 2)
h − 57.5 + 57.5 ≥ −7.5 + 57.5 (Add 57.5 to both sides)
h ≥ 50
So, h ≤ 65 and h ≥ 50
Solution Graph is also attached as shown in attached figure a.
Hence, h − 57.5 ≤ 7.5 is the absolute values which best represents this restriction, where ( h ) represents height. Hence, option A is correct.
Using same methodology we observe that all other options B, C, and D brings wrong values which is as follows:
 h+7.5≤65 brings h≤57.5 and h≥−72.5
 h+50≤65 brings h≤15 and h≥−115
 h+65≤50 brings h≤−15 and h≥−115
Hence, from all discussion, we conclude that h − 57.5 ≤ 7.5 is the absolute values which best represents this restriction, where ( h ) represents height, as it brings h ≤ 65 and h ≥ 50. Hence, option A is correct.
