It costs $10 to go to Pete's Pottery Place to paint custom bowls at a cost of $3.50 per bowl. Janelle plans to paint bowls 5 days this month and then paint b bowls on each day so she can sell them at a craft fair. Which equation represents Janelle's total cost c for the month?

a is the right answer

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
