9 u |
1 u |
8 u |
The amount that Luis had left is the same. Make the numerators the same. LCM of 4 and 8 is 8.
4x29x2 of his money =
89 of his remaining money
818 of his money =
89 of his remaining money
Amount that Luis spent on the sweater = 9 u
9 u = 135
1 u = 135 ÷ 9 = 15
Amount that Luis had at first
= 18 u
= 18 x 15
= $270
Answer(s): $270
