(a)
Amount that Opal spent
=
12 x 6 u
= 3 u
Amount that Wesley spent
=
25 x 1 u
= 0.4 u
Amount that Opal and Wesley spent
= 3 u + 0.4 u
= 3.6 u
3.6 u = 1908
1 u = 1908 ÷ 3.6 = 530
Amount that Opal and Wesley had altogether at first
= 6 u + 1 u
= 7 u
= 7 x 530
= $3710
(b)
Amount that Wesley spent on the hoodie
=
14 x 0.6 u
= 0.15 u
Fraction of Wesley's original amount that he spent on a hoodie
=
0.151 =
0.15 x 1001 x 100=
15100=
320 Answer(s): (a) $3710; (b)
320
