Answer 1

Answer-

The price of gas will be $4.2

Solution-

Gas prices in shelby county = $3.00 per gallon

Market scientist predicts a 40% increase in the price of gas in the coming month.

So the new price will be,

$=3+(3\times \dfrac{40}{100})$

$=3+(3\times 0.4)$

$=3+1.2$

$=4.2$

Therefore, the price of gas will be $4.2

Answer 2

$4.20
3x.40=1.20
Then you add $3+1.20
