10 u |
The amount that Carl had left is the same. Make the numerators the same. LCM of 5 and 10 is 10.
5x29x2 of his money =
1011 of his remaining money
1018 of his money =
1011 of his remaining money
Amount that Carl spent on the sweater = 7 u
7 u = 63
1 u = 63 ÷ 7 = 9
Amount that Carl had at first
= 18 u
= 18 x 9
= $162
Answer(s): $162
