Question

The cost to place a phone call to Tokyo was $3.17 for the first minute plus $1.19 for each additional minute. What was the cost of a 5-minute phone call?

Answer 1

It would be $7.93 for the 5 minute phone call.

Answer 2

Answer:

sorry there was a mistake on my last answer.

so basically your equation would be 3.17+1.19(n-1)

in this case, it would be 3.17+1.19(5-1)

3.17+1.19(4)

3.17+4.76

7.93

the cost of a 5-minute phone call would  be $7.93
