Darcy gave her beauty technician a $5.40 tip. The tip was 12% of the cost of the procedure. Write an equation to find b, the cost of the procedure.

Cost of procedure is $45

Step-by-step explanation:

In this question, we are concerned with finding the cost of the procedure, given the tip amount and the percentage of which it is of the procedure cost.

From the question, we are told that the cost of the procedure is b

Mathematically, 12% of b = tip

Thus,

12/100 * b = 5.4

12b = 5.4 * 100

12b = 540

b = 540/12

b = $45

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
