1: A woman buys a car making a $3,000 down payment and then agrees to make 48 monthly payments of $360. What is the total cost of the car?

2: Last week a man worked 12 hours a day for 5 days. This week he worked 57 hours. How many hours did he work in all?

please show how you got your 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

Step-by-step explanation:

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
