(a)
Amount that Yen spent
=
15 x 6 u
= 1.2 u
Amount that Ahmad spent
=
45 x 1 u
= 0.8 u
Amount that Yen and Ahmad spent
= 1.2 u + 0.8 u
= 5 u
5 u = 1340
1 u = 1340 ÷ 5 = 268
Amount that Yen and Ahmad had altogether at first
= 6 u + 1 u
= 7 u
= 7 x 268
= $1876
(b)
Amount that Ahmad spent on the skirt
=
25 x 0.2 u
= 0.08 u
Fraction of Ahmad's original amount that he spent on a skirt
=
0.081 =
0.08 x 1001 x 100=
8100=
225 Answer(s): (a) $1876; (b)
225
