Equate P as 62.10 since we are looking for the MAX value for x (then a legitimate one if necessary)
(20 + 0.5x) + (3 + 0.075x) = 62.1
= 0.575x + 23 = 62.1
x = (62.1-23)/0.575
x = 680
White paint is $17.50 per gallon so 3 1/2 gallons would be
17.50 * 3.5 = 61.25
And then blue paint is $19 per gallon so 1 3/4 gallons would be
19 * 1.75 = 33.25
Now add
61.25 + 33.25 = 94.5
The total cost would be $94.50
