Ethan scored the same number of points in his first 2 games. He scored 10 points in the third game. He scored a total of 32 points in all three games. How many points did Ethan score in each of the first two games?

• *p for # of points Ethan scored in each of the first two games

  3p - 10 = 32

  p = 14 points in each of the first two games

• *p for # of points Ethan scored in each of the first two games

  2p - 10 = 32

  p = 21 points in each of the first two games

• *p for # of points Ethan scored in each of the first two games

  2 + 10p = 32

  p = 3 points in each of the first two games

• *p for # of points Ethan scored in each of the first 2 games

  2p + 10 = 32

  p = 11 points in each of the first two games

Connor bought 5 bags of chips and a Gatorade. He spent a total of $7. The Gatorade cost $3. Each bag of chips cost the same amount. What was the cost of each bag of chips?

• *c for cost of each bag of chips

  3 + 5c = 7

  c = $0.80 for each bag of chips

• *c for cost of each bag of chips

  3c + 5 = 7

  c = $0.67 for each bag of chips

• *c for cost of each bag of chips

  5c - 3 = 7

  c = $2 for each bag of chips

• *c for cost of each bag of chips

  3c - 5 = 7

  c = $4 for each bag of chips

A group of 5 friends went to the movies. They had ONE $10-off discount. Each friend spent the same amount on each ticket. They spent a total of $53.75, AFTER the discount was taken off. What was the ORIGINAL price of each movie ticket, BEFORE the discount was taken off?

• *c for cost of each ticket before discount

  5c + 10 = 53.75

  c = $8.75 was the cost of each ticket before the discount

• *c for cost of each ticket before discount

  10c + 5 = 53.75

  c = $4.88 was the cost of each ticket before the discount

• *c for cost of each ticket before discount

  5(c + 10) = 53.75

  c = $0.75 was the cost of each ticket before the discount

• *c for cost of each ticket before discount

  5c - 10 = 53.75

  c = $12.75 was the cost of each ticket before the discount

During the summer, Cameron works 26 hours a week at a part-time job. He works 6 hours on the weekends and the same number of hours each weekday. How many hours does Cameron work each weekday?

• *h for # of hours Cameron works each weekday

  7 + 2h = 26

  h = 9.5 hours each weekday

• *h for # of hours Cameron works each weekday

  6 + 5h = 26

  h = 4 hours each weekday

• *h for # of hours Cameron works each weekday

  7h + 5 = 26

  h = 3 hours each weekday

• *h for # of hours Cameron works each weekday

  2h + 6 = 26
