$3.38

Step-by-step explanation:

Hello, I think I can help you with this.

you can solve this by using a simple rule of three

Step 1

the cost per minute is increased by 30%, it means you have to pay 130% of the original price, or you can find the 30% and add this value to the initial cost, it is exactly the same

if

$2.06 ⇔100 %

$x?  ⇔130%

do the relation and solve for x

so, the new price is $3.38.

Step 2

check finding the 30% and adding this value to the initial cost

$2.06 ⇔100 %

$x?  ⇔30%

do the relation and solve for x

$ 0.78+$2.6=$3.38

$3.38 =$3.38 ,ok

Have a good day.
