Answer:
$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
\(\frac{2.06}{100}=\frac{x}{30}\\\\isolate\ x\\x=\frac{30*2.6}{100}\\ x=\frac{75}{100} \\x=0.78\)
$ 0.78+$2.6=$3.38
$3.38 =$3.38 ,ok
Have a good day.
