1. The cost of 6 boxes of cereal and blueberries for $4.98 totaled $26.46. How much was each
   box of cereal?

x = cost of a box of cereal

Solution:

6 푥푥+ 4. 98 =26. 46

6 푥푥=21. 48

6 푥푥

6 =

푥푥=$3. 58

Each box of cereal costs $3.58.

2. Together, Susan and Laura earned $95 babysitting during the month of September. Susan
   earned twelve dollars more than Laura. How much did each girl earn during September?

x = Laura’s earnings

Solution:

푥푥=Laura

푥푥+ 12 =Susan

푥푥+푥푥+ 12 = 95

2 푥푥+ 12 = 95

− 12 – 12

2 푥푥= 83

푥푥=$41. 50

Laura: 푥푥=$41.50
