an online sporting goods store charges $12 for a pair of athletic socks. shipping is $2 per order. write an expression that hana can use to find the total cost in dollars for ordering n pairs of socks

1 Answer

  • For one pair of socks you pay $12 plus $2 shipping.

    Let's use x as the variable for how many pairs of socks someone might buy.

    If someone buys 5 pairs of socks, they will pay $62. $12 * 5 + $2

    So, we can write the expression as 12x + 2.
