Question

At store A, erasers are sold individually. The cost y of x erasers is represented by the equation y=0.75x. The costs of erasers at store B are shown in the graph.

Which of the following statements are true? Select all that apply.


A) The erasers at store A cost $0.75 each.

B) The erasers at store B cost $0.25 each.

C) The erasers at store B cost more.

D) The erasers cost the same at both stores.

E) The erasers at store A cost more.

Answer 1

A, B, E

Explanation:

When you put x=1 into the cost formula for store A, you find one eraser costs $0.75. (Makes statement A true.)

When you look up the cost of 1 eraser on the graph, you see it is $0.25 at store B. (Makes statement B true.)

Since statements A and B are true, statement E is true, and statements C and D are false.

The true statements are A, B, E.
