(a)
Amount that Lynn spent
=
15 x 3 u
= 0.6 u
Amount that Howard spent
=
25 x 1 u
= 0.4 u
Amount that Lynn and Howard spent
= 0.6 u + 0.4 u
= 3 u
3 u = 1197
1 u = 1197 ÷ 3 = 399
Amount that Lynn and Howard had altogether at first
= 3 u + 1 u
= 4 u
= 4 x 399
= $1596
(b)
Amount that Howard spent on the skirt
=
25 x 0.6 u
= 0.24 u
Fraction of Howard's original amount that he spent on a skirt
=
0.241 =
0.24 x 1001 x 100=
24100=
625 Answer(s): (a) $1596; (b)
625
