= 1 -
18 =

The remainder and the total amount on the gas stove and the savings are the same. Make the remainder and the total amount on the gas stove and the savings the same. LCM of 7 and 4 is 28.
Total salary = 32 u
Amount spent of the juicer = 4 u
Amount spent on the gas stove = 21 u
Amount of savings = 7 u
7 u = 259
1 u = 259 ÷ 7 = 37
Yoko's salary
= 32 u
= 32 x 37
= $1184
Answer(s): $1184
