Answer:

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
