Question

A salesperson has January sales of $20,000(1,$20,000) and April sales of $80,000 (4,$80,000). What is the rate of change?

Answer 1

60000/4 pr 15000

Explanation:

Rate of change = change in population / change in time

80000 - 20000 = 60000

January to April is 4 months

so the rate of change will be 60000/4 or 15000
