Question

Last week, Hazel paid $32 to have 50 reports printed. This week, she paid $57 to have 100 reports printed. Assume the relationship is linear. Which equation models the relationship between the number of reports, x, and the cost, y?

y = 2x + 68
y=1/2x+7
y=1/2x+34
y = 2x + 34

Answer 1

i'm pretty sure it's (1/2×50) +7
and (1/2×100)+7
others don't work.

Answer 2

The answer is the second one. Y=1/2x+7
