Apply System of Equations

You sell tickets for admissions to your school play and collect a total of $104. Admissions prices are $6 for adults and $4 for children. You sold 21 tickets. Which system of equations represents this scenario.

• a + c = 104

  6a + 4c = 21

• 6 + 4 = a

  104 - 21 = c

• a + c = 21

  6a + 4c = 104

• a + c = 21

  6a - 4c = 104

You bought the meat for Saturday's cookout. A package of hot dogs costs $1.60 and a package of hamburgers costs $5. You bought a total of 8 packages of meat and you spent $23. Which system of equations represents this word problem?

• x - y = 8

  1.60x - 5y = 23

• x + 1.60x = 8

  y + 5y = 23

• x + 5y = 8

  1.60x + y = 23

• x + y = 8

  1.60x + 5y =23

Phillip collects two kinds of baseball cards. The first kind is worth $5.50 each. The second kind is worth $3.90 each. If he has 46 cards altogether, and they are worth a total of $209. 80. Write a system of equations to represent this scenario.

• y = x + 46

  209.80 = -5.50x + 3.90y

• x + y = 46

  5.50x + 3.90y = 209.80

• x + y = 209.80

  5.50x + 3.90y = 46

• 209.80 - 46 = y

  5.50 + 3.90 = x
