Answer
7.
Explanation:
Step1: Calculate total amount paid
The number of months in 2 years is $2\times12 = 24$ months. The monthly payment is $95$, so the total of monthly - payments is $95\times24=2280$. She made a $50$ down - payment. So the total amount she paid is $2280 + 50=2330$.
Step2: Calculate total interest
The cost of the computer is $2100$. The total interest paid is the total amount paid minus the cost of the computer, so $2330−2100 = 230$.
Answer:
$230$
8.
Explanation:
Step1: Calculate down - payment amount
The down - payment is $20%$ of $1200$. So the down - payment amount is $0.2\times1200 = 240$.
Step2: Calculate total of monthly payments
The number of months in 2 years is $2\times12=24$ months. The monthly payment is $45$, so the total of monthly payments is $45\times24 = 1080$.
Step3: Calculate total amount paid
The total amount paid is the sum of the down - payment and the total of monthly payments, so $240+1080 = 1320$.
Step4: Calculate total interest
The cost of the refrigerator is $1200$. The total interest paid is $1320−1200=120$.
Answer:
$120$
9.
Explanation:
Step1: Calculate amount to be paid in installments
The cost of the game player is $1650$, and the down - payment is $100$. So the amount to be paid in installments is $1650 - 100=1550$.
Step2: Calculate number of months
The time is $1.5$ years. The number of months is $1.5\times12 = 18$ months.
Step3: Calculate total of minimum monthly payments
The minimum monthly payment is $20$. The total of minimum monthly payments for 17 months (because we want to find the last payment) is $20\times17 = 340$.
Step4: Calculate last payment
The last payment is the amount to be paid in installments minus the total of minimum monthly payments for 17 months, so $1550−340 = 1210$.
Answer:
$1210$
10.
Explanation:
Step1: Calculate total amount paid
The number of months in 2 years is $2\times12 = 24$ months. The monthly payment is $70$, so the total amount paid is $70\times24=1680$.
Step2: Calculate total interest
The cost of the couch is $960$. The total interest paid is the total amount paid minus the cost of the couch, so $1680−960 = 480$.
Answer:
$480$
