($3.91)(0.09) = $0.3519

$3.91 + 0.3519 = $4.2619 per gallon

if you're looking for the total expense next year:

($4.2619)(370 gallons) = $1,576.903

The approximate heating expense will be $1,576.903.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Last winter the romano family used 370 gallons of oil at a price of $3.91 per gallon. If the price increases 9% next year then,

($3.91)(0.09) = $0.3519

Now, we have

$3.91 + 0.3519 = $4.2619 per gallon

The total expense next year:

= ($4.2619)(370 gallons)

= $1,576.903

Therefore, the approximate heating expense will be $1,576.903.
