MULTIPLE CHOICE QUESTION

Jerry has a new job and earns a salary of $45,000. Victoria has a new job and earns a salary of $54,000. Jerry will receive a salary increase of $2,500 per year, and Victoria will receive a salary increase of $1,500 per year. Which equations can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria?

45,000x + 2,500x = 54,000x + 1,500x

45,000x + 2,500 = 54,000x + 1,500

45,000 + 2,500x = 54,000 + 1,500x

45,000x + 2,500x = 54,000x + 1,500

Two eighth grade classes are selling raffle tickets to raise money. One class is selling tickets for $2.50 each and has already raised $350. The other class is selling tickets for $3.00 each and has already raised $225. Which equations can be used to find t, the number of tickets each class needs to sell so that the total amount raised is the same for both classes?

3t + 350 = 2.50t + 225

350t + 2.50 = 225t + 3

2.50t + 350 = 3t + 225

Brody rode his bicycle on two different days. The first day he rode 7 miles per hour and started 1 mile from his house. The second day he started from his house and rode 10 miles per hour. What is x, the number of hours that Brody would have to ride his bicycle to travel the same distance on both days?

7x + 1 = 10x

7 + 1x = 10x

7x + 1 = 10

7x + 1x = 10x

Sierra has a bucket that originally contained 340 fl oz of water and is being filled at a rate of 5 fl oz per minute. Brian has a bucket that originally contained 650 fl oz of water and is being drained at a rate of 8 fl oz per minute. What is x, the number of minutes that need to pass in order for the two buckets to contain the same amount of water?

340 + 5x = 650 + 8x

340x + 5 = 650x - 8

340 + 5x = 650 - 8x

340 - 5x = 650 - 8x

A town's population is 14,000, and it is increasing by 160 people every year.  A nearby town has a population of 24,000, and it is decreasing by 200 people every year.  In about how many years will the populations of the towns be equal?
14,000 + 160y = 24,000 - 200y
14,000 + 160y = 24,000 + 200y
14,000y + 160 = 24,000y - 200
14,000 - 160y = 24,000 - 200y

The temperature in your town is 21° and rising 1.5°every hour.  Your friend lives far away and the temperature is 28° and falling 2° every hour.  In how many hours will the temperature be equal?
21 + 1.5h = 28 + 2h
21 + 1.5h = 28 - 2h
1.5 + 21h = 2 + 28h
21 - 1.5h = 28 - 2h
