The remainder and the total amount on the lamp and the savings are the same. Make the remainder and the total amount on the lamp and the savings the same. LCM of 2 and 3 is 6.
Total salary = 15 u
Amount spent of the stand mixer = 9 u
Amount spent on the lamp = 4 u
Amount of savings = 2 u
2 u = 68
1 u = 68 ÷ 2 = 34
Victoria's salary
= 15 u
= 15 x 34
= $510
Answer(s): $510
