25The amount left is repeated.
Make the numerators the same. LCM of 2 and 1 is 2.
25 Remaining amount =
110 Total amount
2x15x1 Remaining amount =
1x210x2 Total amount
25 Remaining amount =
220 Total amount
Amount that Tammy spent on the blazer
= 18 u - 3 u
= 15 u
15 u = 225
1 u = 225 ÷ 15 = 15
Total amount that Tammy spent
= 15 u + 3 u
= 18 u
= 18 x 15
= $270
(b)
Total amount that Tammy had at first
= 20 u
= 20 x 15
= $300
Answer(s): (a) $270; (b) $300
