Question

Jenny has six basketball teams, each team needs new shoes for an upcoming tournament, and she spent 630 dollars on all the shoes thus far. Each pair of shoes cost 6 more than last year's pairs of shoes.

How much did last year's shoes cost?

Answer 1

SInce there are six teams and each pair of shoes for each individual player is $630, set up this equation:

630 (total thus far) = 6x (six times the cost of last year)

630/6 = x

This means that last year's cost was $105.
