The local supermarket is having a holiday special on lollipops. The rainbow lollipops, x, cost $2 and the blue lollipops, y, cost $1. At the end of the day, the supermarket sold a total of 185 lollipops with a total profit of $320. Given the system of equations below, find the solution and what it means in context to the situation. 2x+y=320 y=-x+185 *

135 rainbow lollipops were sold ($270) and 50 blue lollipops were sold ($50).

Step-b-step explanation:

Cost of rainbow lollipops: 2

Cost of blue lollipops: 1

2x + y = 320

x + y = 185, y = 185 - x

Solve with substitution:

2x + (185 - x) = 320

x = 135

y = 50

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
