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
Cost of 225 minutes
A(225) = 0.15(225) + 8
A(225) = $41.75
Therefore,
Minutes = 225
Cost = $41.75
