Alawn service charges $30, plus $15 per hour. if x represents the number of hours, then the expressions for the total charge is 15 x +30. which table shows the total charge.

It's going to be the first one...

How you solve this is just insert the number of hours you want for X then solve the equation.

15 * 1 = 15

15 + 30 = 45

15 * 3 =45

45 + 30 = 75

He paid = $20,500

Step-by-step explanation:

Let the amount he bought the car originally be X

so from the statement,

(2/5)*X + $200 = $8,400

(2/5)*X = $8,400 - $200

solving for X

X = $8200 * 5/2

X = $20,500
