(a)
Amount that Tiffany spent
=
15 x 3 u
= 0.6 u
Amount that Dylan spent
=
25 x 1 u
= 0.4 u
Amount that Tiffany and Dylan spent
= 0.6 u + 0.4 u
= 3 u
3 u = 2088
1 u = 2088 ÷ 3 = 696
Amount that Tiffany and Dylan had altogether at first
= 3 u + 1 u
= 4 u
= 4 x 696
= $2784
(b)
Amount that Dylan spent on the jacket
=
25 x 0.6 u
= 0.24 u
Fraction of Dylan's original amount that he spent on a jacket
=
0.241 =
0.24 x 1001 x 100=
24100=
625 Answer(s): (a) $2784; (b)
625
