Question

gas prices are projected to increase by 124% by april 2015. a gallon of gas currently costs $3.80. what projected cost of a gallon of gas for april 2015?

Answer 1

$8.51

Explanation:

Remember that

`100\%+124\%=224\%=224/100=2.24`

we know that

For April 2015 the projected cost of a gallon of gas is equal to multiply the currently cost by the percentage increase

so

The linear equation is equal to

`3.80(2.24)=\$8.51`
