Answer: He should receive $8.15.
Explanation:
Cost per flat of petunias = $5.25
Cost for 2 flats of petunias = 2 ($5.25) = $ 10.50
Cost per flat of daisies = $7.65
Cost for 3 flat of daisies = 3 ($7.65) = $22.95
Cost per flat of begonias = $8.40
Now, Total bill = Cost for 2 flats of petunias + Cost for 3 flat of daisies + cost of 1 flat begonias
= $ (10.50+22.95+8.40)
= $ 41.85
If he pays $50, then change =$ 50 - Total bill
= $(50-41.85)
= $ 8.15
Hence, He should receive $8.15.
