Equations and Inequalitites

Candi has boxes of candles that weigh 5.5 pounds

each. Write an equation to find b, the number of

boxes Candi has if they weigh a combined total of

38.5 pounds.

• 5.5x = 38.5

• 38.5x = 5.5

• 5.5 + x = 38.5

• 38.5 + x = 5.5

Jazmin went to QT and bought bags of hot fries for

$2.25 each and a soda for $1.50. Jazmin spent

$12.75. Write an equation to determine b, the

number of bags of hot fries that Jazmin bought.

• 1.5b + 2.25 = 12.75

• 12.75b + 1.5 = 2.25

• 12.75b + 2.25 = 1.5

• 2.25b + 1.5 = 12.75

Rachel bought a dozen balloons and a bag of party

hats for a party. The bag of party hats cost $9.95. If

Rachel spent a total of $33.83 on the balloons and

party hats, write an equation to find b, the cost of

each balloon.

• 12b + 9.95 = 33.83

• 33.83b + 12 = 9.95

• 12b + 33.83 = 9.95
