Answer 1

Answer:

if you’re looking for a equation it could be “ 24c + 15 = 687 “Step-by-step explanation:

Answer 2

Beginner courses cost $18 while advanced courses cost $24.

Let b represent the cost of the beginner classes and a represent the cost of advanced classes.

The beginner costs 6 more than half the cost of the advanced class. Hence:

b = a/2 + 6  

2b = a + 12

2b - a = 12    (1)

Last week they taught 7 beginner classes and 11 advanced classes and earned $390, Hence:

7b + 11a = 390   (2)

Solving equations 1 and 2 simultaneously gives: b =  18, a = 24

Beginner courses cost $18 while advanced courses cost $24.
