(a)
Amount that Marion spent
=
15 x 3 u
= 0.6 u
Amount that Warren spent
=
25 x 1 u
= 0.4 u
Amount that Marion and Warren spent
= 0.6 u + 0.4 u
= 3 u
3 u = 1896
1 u = 1896 ÷ 3 = 632
Amount that Marion and Warren had altogether at first
= 3 u + 1 u
= 4 u
= 4 x 632
= $2528
(b)
Amount that Warren spent on the shirt
=
14 x 0.6 u
= 0.15 u
Fraction of Warren's original amount that he spent on a shirt
=
0.151 =
0.15 x 1001 x 100=
15100=
320 Answer(s): (a) $2528; (b)
320
