The doctor's cost for a set of scrubs is $47.60
Given:
cost = $34
mark-up = 40%
Mark up based on cost:
$34 * 40%/100% = $13.60 mark up
New price or doctor's cost:
$34 + 13.60 = $47.60
It can also be computed this way.
$34 * 140%/100% = $47.60
It think thw anwser is 15
multiply the 2 numbers together than divide by 2
7 1/2 = 15/2
12 2/3 = 38/3
15/2 * 38/3 = 570/6 =95
95/2=47.5 square feet
1/2 (6x - 10) + 10 = 5x - 13
(6x/2) - (10/2) + 10 = 5x - 13
3x - 5 + 10 = 5x - 13
3x - 5x = -13 + 5 - 10
-2x = -18
x = -18 / -2
x = 9
D.) x = 9
