The remainder and the total amount on the television set and the savings are the same. Make the remainder and the total amount on the television set and the savings the same. LCM of 3 and 5 is 15.
Total salary = 25 u
Amount spent of the food processor = 10 u
Amount spent on the television set = 9 u
Amount of savings = 6 u
6 u = 192
1 u = 192 ÷ 6 = 32
Barbara's salary
= 25 u
= 25 x 32
= $800
Answer(s): $800
