David rented a car for his family vacation. The total bill for the car was $622. The cost for one week is $400, plus $37 for each additional day. Use the equation 622=400+37x to find how many additional days David had the car. a) x=3
b) x=8
c) x=37
d) x=6

d) x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

622=37x+400

Step 2: Flip the equation.

37x+400=622

Step 3: Subtract 400 from both sides.

37x+400−400=622−400

37x=222

Step 4: Divide both sides by 37.

37x/37=222/37

x=6

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
