Question

Which equation best describes the pattern in the table below?

Minutes Cost
15 $1.50
30 $3.00
45 $4.50
60 $6.00

A. c = 0.10m
B. m = 0.10c
C. c + m = 0.10
D. c - m = 0.10

Answer 1

A

Explanation:

The pattern in the table adds 1.50 for ever 15 minutes. That means per minute it adds
`(1.5)/(15) =0.10` or 10 cents. This means you multiply each minute by 0.10 to find the cost. This is the equation c = 0.10m.
