Answer 1

Hyunjin has 27,500 left.

Changbin & Han have 70 lightsticks left.

Explanation:

A) 45 × 500 = 22500 50,000 - 22500 = 27500

B) 145 - 75 = 70

Answer 2

a) he would have 27500 won

b) changbin and han would have 70 lightsticks

Explanation:

a)

multiply 45 rings by 500 won to get the total expense

45 x 500 = 22500

then subtract 22500 won from 50000 to get the amount left after the purchase

50000 - 22500 = 27500

this results in 27500 won total

b)

subtract 75 from 145 to get the amount left

145 - 75 = 70
