Answer:
A. $ 31.24.
B. $ 33.34.
Step-by-step Explanation:
Price of Pansies = $1.79.
Price of Marigolds = $1.19.
Price of Zinnias = $0.74.
He plans to buy 10 of one type and 8 each of the other two types of plants.
Since the prices of Pansies > the price of Marigold > the price of Zinnias.
Minimum expenses for Edward:
= 10*(least valued flower) + 8*(other valued flowers)
= 10*(Zinnias) + 8*(Pansies) + 8*(Marigold).
= 10*($ 0.74) + 8*($ 1.79) + 8*($ 1.19)
= $ (7.4 + 14.32 + 9.52)
= $ 31.24.
Maximum expenses for Edward:
= 10*(most valued flower) + 8*(other valued flowers)
= 10*(Lansies) + 8*(Zinnias) + 8*(Marigold).
= 10*($ 1.79) + 8*($ 0.74) + 8*($ 1.19)
= $ (17.9 + 5.92 + 9.52)
= $ 33.34.
