Let x: the number of restaurants gift cards, and y: numbers of movie theaters gift card

50x+20y=450
x+y=15, so x=15-y
50(15-y)+20y=450
750-50y+20y=450
y=10
x=5.
As a result, Mr. Thompson buys 10 movie theaters give cards, and 5 restaurants gift cards. Hope it help!

5 parts per minute times 100 minutes = 500 parts

500/20 = 25 containers are needed
