Answer:
$273.38 per month
Step-by-step explanation:
<u>Monthly Payment Formula</u>

where:
- PMT = monthly payment
- P = loan amount
- i = interest rate per month (in decimal form)
- n = term of the loan (in months)
Given:
- P = $19,500 - $4,000 = $15,500
- i = 2.25% / 12 = 0.0225 / 12
- n = 5 years = 60 months



Use proportion to solve this.
240 miles needs 9 gallons
216 miles needs (9÷240) × 216 = 8.1 gallons
