Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Material cost = $20 (Given)

Lesson cost = $15 (Given)

.............................................................................................

STEP 1: Form equation:

Let x be the number of lessons

Total cost = 20 + 15x

.............................................................................................

STEP 2: Find the number of lessons

Total cost paid = $125

125 = 20 + 15x

15x = 125 - 20

15x = 105

x = 7

.............................................................................................

Answer: The equation is Total cost = 20 + 5x and Bill took 7 lessons.
