Question

The price of an 8-minute phone call is $1.20. What is the price of an 18-minute phone call?

Answer 1

Answer:

$2.70 cents

Step-by-step explanation:

Given the following question:

$1.20\div8$

In order to find the answer, we will find how much it costs each minute by dividing.

$1.20\div8=0.15$
$m=0.15$

Now multiply:
$m=0.15$
$0.15\times18=2.7$
$=2.70$

Which means for an 18-minute phone call it would cost "$2.70 cents."

Hope this helps.

$2.70

Step-by-step explanation:

1.20÷8=0.15

0.15= 1 minute of each call

so

0.15x18=$2.70
