Question

The cost per minute of a conference phone call, originally $2.80, increased by 20%. What is the new price?

A.
$3.00

B.
$3.26

C.
$3.20

D.
$3.36

Answer 1

To solve this you need to find out what 20% of 2.80 is.
So
2.8*.2
=.56
So since 20% of 2.80 is .56 and the price increased by 20% you would add the .56 to the 2.80

2.80+.56=3.36
