Question

Anika buys some items for her soccer uniform: a pair of shorts for $8.58 and several pairs of socks for $4.29 per pair. If she spends $25.74 before taxes, how many pairs of socks does Anika buy?

Answer 1

Having spent a total of $25.74 of which $8.58 was spent on the shorts, Anika has how much money left over to spend on socks? That amount is determined by subtraction:

25.74 - 8.58 = 17.16.

Since each pair of socks costs $4.29 determine how many pair of socks were purchased by answering the question how many 4.29 are in 17.16. The operation that determines that is division.

17.16 / 4.29 = 4. If the result was not a whole number, then the conditions of the problem were stated incorrectly.

Check:

4(4.29) + 8.58 = 17.16 + 8.58 = 25.74
