One gallon costs $ 2.90 , but this cost is projected to increase by 10% in the next 2 years. What is the projected cost of a gallon of gas 2 years from now ?

$3.19

Step-by-step explanation:

A gallon costs $2.90

In the next two years, its cost increases by 10%;

(10÷100) × $2.90

Increased rate =$0.29

The new amount in two years time = the old cost + rate amount

= $2.90 + $0.29

=$3.19

a. 12.5 kg
