Step-by-step explanation:
The horizontal axis is in fractions.
The three lightest are two
pounds & one
pounds. Each cost $4.40 per pound.
So cost = 4.40(5/8+5/8+6/8) = $8.8
Remaining costs 4.80 per pound. We add up the remaining and multiply by 4.80 to get their cost.
cost = 
Hence, total cost = 8.8 + 33.6 = $42.40
