Answer:
1) $636
2) $33,072
Stepbystep explanation:
Percents and decimals can be used together to answer questions about proportions of a number.
One Week
First, we need to find how much Alexander made in commission over one week. We are told that he earns 12% and sold $5,300 of stock. So, we need to find 12% of 5,300.
To find a percentage of a number, we can multiply by the decimal. To turn a percentage into a decimal, move the decimal 2 spots to the right. This means that 12% = 0.12. Then, multiply the whole number by that decimal.
 0.12 * 5300 = 636
Alexander made $636 in commission in one week.
Commission in a Year
Remember that 1 year = 52 weeks.
If Alexander averaged $636 every week, then we can just multiply 636 by 52 to find his income in a year.
 636 * 52 = 33072
So, he made $33,072 in one year.
