Answer:
B
C
Step-by-step explanation:
B= one question equals one minute
C= one minute equals one question
I multiplied 48 times 15 percent which comes to 7.20
7.20 plus 48 equals 55.20
Cost Price for oil change =$27
Charge for the customers =$40
Markup cost = Difference between selling price and cost price =$40-$27=$13
To find the percent of markup, divide the markup cost by the cost price and multiply it by 100.
Markup percent = (13/27)*100
=48.15%
If you mean -1/3x try using y=3x
