SashulF [63]

Answer:

Minutes = 225

Cost = $41.75

Step-by-step explanation:

It is given that:

Cost of Plan A = $8

Per minute cost = $0.15

Let,

m be the number of minutes

A(m) = 0.15m + 8

Cost of Plan B = $17

Per minute cost = $0.11

B(m) = 0.11m + 17

For same cost,

A(m) = B(m)

0.15m+8 = 0.11m + 17

0.15m - 0.11m = 17 - 8

0.04m = 9

Dividing both sides by 0.04

\frac{0.04m}{0.04}=\frac{9}{0.04}\\m = 225

Cost of 225 minutes

A(225) = 0.15(225) + 8

A(225) = $41.75

Therefore,

Minutes = 225

Cost = $41.75
