Question

The relation between the number of tutoring sessions and the earnings are given below. The equation for the given relation is

• A. n = 7e + 5
• B. e = 7n + 5
• C. e = 5n

Answer 1

The correct option is B e = 7n + 5

From the given table, when n= 5, e = 40

When n = 10, e = 75

When n = 15, e = 110

When n = 20, e = 145.

Hence, e is sum of 7 times n and 5.

Hence, the equation that represents the relation is, e = 7n + 5
