Answer:
$60
Step-by-step explanation:
40% of x (original price) is $24
0.4 · x = 60
So the original price is $60
To get a discount price from full price you would multiply the full price by the discount (in this case .40) and to get the full price from discount price you would divide the discount price by 1- discount
So 24/.6= 40
Keep and group -3x+8x which becomes 5x. Then keep -6.
Then it becomes the answer above.
