36 / 50 = $ 0.72 per unit
60 / 80 = $ 0.75 per unit
kazoos
10 / 25 = $ 0.4 per unit
18.50 / 50 = $ 0.37 per unit
27.20 / 80 = $ 0.34 per unit

b.) 10 / 25 = $ 0.4 per unit
c.) he must order 80 kazoos she should
order

Answer 2

Answer:

first let as solve all unit price

whistles 21.25 / 25 = $ 0.85 per unit

60 / 80 = $ 0.75 per unit

kazoos

10 / 25 = $ 0.4 per unit

18.50 / 50 = $ 0.37 per unit

27.20 / 80 = $ 0.34 per unit

a.) $ 0.85 - $ 0.72 = $ 0.13
