Mrs. Jacobson wants to order toy instruments to give as prizes to her music students. The table shows the prices for various ord
er sizes. 25 Items 50 Items 80 Items
Whistles: [21.25] [36.00] [60.00]
Kazoos: [10.00] [18.50] [27.20]
a. What is the difference between the highest until price for whistles and the lowest
unit price for whistles?
b. What is the highest unit price per kazoo?
c. If Mrs. Jacobsen wants to buy the item with the lowest unit price, what item should
she order and how many of that item should she order?
First let as solve all unit pirce whistles 21.25 / 25 = $ 0.85 per unit 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 a.) $ 0.85 - $ 0.72 = $ 0.13 b.) 10 / 25 = $ 0.4 per unit c.) he must order 80 kazoos she should order
1 kg = 0.001 metric tons..so 14327 kg = (14327 * 0.001) = 14.327 metric tons and if 1 metric tons saves 17 trees....then 14.327 tons saves : 14.327 * 17 = 243.559 saved trees...and since u cant have 0.559 trees, u would round to 243 trees
