Oil prices are projected to increase by 30% by next April. A quart of oil currently costs $1.65. What is the projected cost of a gallon of oil next April? Round your answer to the nearest hundredth.

The projected cost of a gallon of oil next April is $8.58

Step-by-step explanation:

Let's calculate the current cost of a gallon of oil.

Since one gallon equals 4 quarts, the actual value of the gallon of oil is

$1.65*4=$6.60

We know that oil prices are projected to increase by 30% by next April, thus the projected cost of the gallon of oil can be calculated by first knowing the increase and then add it to the actual cost.

The increase is 30% of $6.60, or

30 * 6.60 / 100 = $1.98

The new price will be:

$6.60 + $1.98 = $8.58

The projected cost of a gallon of oil next April is $8.58
