(a)
Fraction of the remaining amount left
= 1 -
37=
47The amount left is repeated.
Make the numerators the same. LCM of 4 and 1 is 4.
47 Remaining amount =
18 Total amount
4x17x1 Remaining amount =
1x48x4 Total amount
47 Remaining amount =
432 Total amount
Amount that Lynn spent on the vest
= 28 u - 3 u
= 25 u
25 u = 350
1 u = 350 ÷ 25 = 14
Total amount that Lynn spent
= 25 u + 3 u
= 28 u
= 28 x 14
= $392
(b)
Total amount that Lynn had at first
= 32 u
= 32 x 14
= $448
Answer(s): (a) $392; (b) $448
