Question

Eric and Pam are each saving money to buy a car. Eric has $750 saved and will save an additional $30 a week. Pam has $1,200 saved and will save an additional $20 a week. How many weeks will it take Eric and Pam to save the same amount of money? How much money will they have saved?

Answer 1

750+30x=1200+20x

x representing number of weeks.

750 +10x = 1200

10x = 450

x =45

It will take 45 weeks for both parties to have the same amount of money.

After 45 weeks the amount of money saved would be 750 +30(45) =2100

Answer 2

w represents the number of weeks

750 + 30w = 1200 + 20w

Can you solve for w and answer?
