Identical shirts and saved the rest.
(a)
What fraction of Ivan's money was pent on the 3 shirts?
(b)
The watch cost $120 more than one shirt. How much money dld Ivan
save?

Answer 1

(a) 2/5 * 3/4 = 3/10 of total
so a shirt is 1/10 of total
so
1/4 on watch
3/10 on shirts
watch = 1/4 total = 120 + 1/10 total
(5/20 - 2/20) total = 120
3 * total = 2400
total = 600
watch = 180
shirts =180
remainder = 240 saved

Answer 2

3 * total = 2400
total = 800
