Question

The price of a 7-minute phone call is $1.05 . What is the price of a 14-minute phone call?
​

Answer 1

Maybe try 2.10 that should be the answer

Answer 2

$2.10

Explanation:

Since 7 minutes is half of 14 minutes, the price of the 14 minutes phone call must be two times the cost of the 7 minute phone call.

`(14)/(7)`= 2

$1.05 should be multiplied with 2 to find the price of the 14 minute phone call.

$1.05 × 2 = $2.10
