Final answer:
Trisha spent a total of $28,800 on her new car, which includes a $1,800 down payment and $375 monthly payments over 6 years.
Step-by-step explanation:
To calculate the total cost of the car that Trisha bought, we need to add the initial down payment to the sum of the monthly payments made over the 6 years. The calculation goes as follows:
Down payment: $1,800
Monthly payment: $375
Total number of monthly payments: 6 years x 12 months/year = 72 months
Total cost of monthly payments: 72 months x $375/month = $27,000
Total cost of the car: Down payment + Total cost of monthly payments = $1,800 + $27,000 = $28,800
Therefore, Trisha spent $28,800 in total for her new car.
