Pedro wants to buy some shirts over the internet. each shirt costs $10.01 and has a shipping cost of $9.94 per order. if pedro wants to spend no more than $70 for his shirts, which inequality shows the maximum number of shirts, p, that he can buy? 9.94 + 10.01p ≤ 70, so p ≤ 6 9.94 − 10.01p ≤ 70, so p ≤ 7 9.94p + 10.01p ≤ 70, so p ≤ 8 9.94p − 10.01p ≤ 70 ≤ 60, so p ≤ 9

it’s A I took the test

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
