Answer:
1. $20280
2. 117 h
Step-by-step explanation:
1.
to know the value of the car we have to add all the monthly payments with the $ 3000 that she paid at the beginning
x = car value
x = $3000 + 48 * $360
x = $3000 + $17280
x = $20280
The total cost of the car is $20280
2.
To know how many hours I work in total we have to add the hours I work in each day 5 times with the 57 hours I work the following week
x = hours that work in all
x = 5 * 12 + 57
x = 60 + 57
x = 117
work for 117 hours in all
1) the down payment made for the car is $3000.
She then agrees to make 48 monthly payments of $360. It means that the total monthly payments in 48 months is
48 × 360 = $17280
The total amount that she paid for the car is
17280 + 3000 = $20280
2) Last week a man worked 12 hours a day for 5 days. It means that the total number of hours he worked last week is
12 × 5 = 60 hours
This week, he worked 57 hours. It means that the total number of hours he worked is
60 + 57 = 117 hours
Answer: the third one
X= 4. Y = 3.
If you have a graphing calculator, put the first equation into Y1. And second equation into Y2. Then, find the intersection of the two equations. That's how you find your answer.
The answer would be $2.70
