Sasha wants to buy some dresses over the Internet. Each dress costs $7.15 and has a shipping cost of $9.95 per order. If Sasha wants to spend no more than $60 for her dresses, which inequality shows the maximum number of dresses, p, that she can buy? (5 points)

a
9.95 − 7.15p ≤ 60, so p ≤ 4

b
9.95p + 7.15p ≤ 60, so p ≤ 5

c
9.95p − 7.15p ≤ 60, so p ≤ 6

d
9.95 + 7.15p ≤ 60, so p ≤ 7

Mercury · Answer

if each dress costs 7.15, then (p) dresses cost 7.15*p, right?

add this onto the flat shipping fee of 9.95

set the result less than or equal to the budget (60)

write this as an inequality, then solve
