Answer 1

Answer is: $320


Explanation: $20 + 50% of $320 in sales =$180 and, $100 + 25% of $320 in sales = $180

Answer 2

Answer:

C $320

Step-by-step explanation:

write equations for the two possible choices

situation 1:

y₁ = 20 + 0.5x, where y is the total price the club pays and x is the sales

** note i use 0.5 instead of 50, since 50 would represent 5000%

y₂ = 100 + 0.25x, where y is the total price the club pays and x is the sales

now set the two equations equal to each other

20 + 0.5x = 100 + 0.25x

isolate x by subtracting 0.25x and 20 from each side

20 + 0.5x - 0.25x - 20 = 100 + 0.25x -0.25x -20

0.25x = 80

divide both sides by 0.25

$\frac{0.25x}{0.25}$ = $\frac{80}{0.25}$

x = 320
