= 1 -
17 =

The remainder and the total amount on the microwave oven and the savings are the same. Make the remainder and the total amount on the microwave oven and the savings the same. LCM of 6 and 5 is 30.
Total salary = 35 u
Amount spent of the stand mixer = 5 u
Amount spent on the microwave oven = 12 u
Amount of savings = 18 u
18 u = 612
1 u = 612 ÷ 18 = 34
Shannon's salary
= 35 u
= 35 x 34
= $1190
Answer(s): $1190
