4x2 =
8 u |

The amount of savings that Usha has at first and in the end remains unchanged. Make the amount of savings that Usha has the same. LCM of 2 and 1 is 2.
Amount that Owen saved
= 8 u - 1 u
= 7 u
7 u = 840
1 u = 840 ÷ 7 = 120
Total savings at first
= 2 u + 1 u
= 3 u
= 3 x 120
= $360
Answer(s): $360
