Diego works at a toy store. His boss tells him to order 420 stuffed bears and toy cars. He must order 4 stuffed bears for every 3 toy cars.

a) If he must order 9 large stuffed bears for every 7 small stuffed bears, how many of each stuffed bear should he order?

b) If Diego must order 7 toy racecars for every 3 toy trucks, how many of each toy car should he order?

b+c = 420 so c = 420 - b

c = (3/4) b
so
3 b/4 = 420 - b
3 b = 1680 - 4 b
7 b = 1680
b = 240 bears total

b = sb + bb but bb = (9/7)sb
so
240 = sb +(9/7) sb = (16/7)sb
sb = 105 small bears
bb = 240 - 105 = 136 big bears
