(a)
Amount that Kathy spent
=
14 x 4 u
= 1 u
Amount that Will spent
=
45 x 1 u
= 0.8 u
Amount that Kathy and Will spent
= 1 u + 0.8 u
= 3.2 u
3.2 u = 1888
1 u = 1888 ÷ 3.2 = 590
Amount that Kathy and Will had altogether at first
= 4 u + 1 u
= 5 u
= 5 x 590
= $2950
(b)
Amount that Will spent on the blouse
=
25 x 0.2 u
= 0.08 u
Fraction of Will's original amount that he spent on a blouse
=
0.081 =
0.08 x 1001 x 100=
8100=
