A photographer needs $4000 to purchase a printer for her new business. Each photo that she prints will cost an additional $3.56 for ink. She plans on selling each photo for $9.99 each Which of the following equations represents the profit, P(x), the photographer will make for each photo, x, that she sells?
A
P(x) = 6.43x + 4000
B
P(x) = 6.43x - 4000

on friday there were 15 birds

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
