The science club is comparing options for purchasing new T-shirts. One company charges a $100 base fee plus an additional $3.50 per shirt. A second company charges a $120 base fee but only an additional $2.50 per shirt. The given expression represents the difference of the two companies’ average cost per shirt.

Which expression is equivalent to the expression representing this situation?

Just took the test

Answer 2

A

Explanation:

We have a common denominator, so we can just subtract the numerators, and leave it over the given denominator.

[(3.5x+100)-(2.5x+120)]/x

(3.5x+100-2.5x-120)/x

(1x-20)/x

(x-20)/x=A
