Answer:
1 cup = 8.4 g, 1 cup = 88% peanut butter
100% = 8.4 g
88% = x, where x is the mass of PB in the cup
x = (88* 8.4)/ 100
x= 7.392g
1 bag = 23 cups, 1 bag = $ 5.99
1 cup = 7.392 g of PB
23 cups = 170.016 g of PB by mass
1 bag = 170.016 g of PB by mass = 0.3745 lbs of PB
600 lbs = how many bags
= 600 lbs ÷ 0.3745 lbs
= 1602.15 bags
1 bag = $5.99
1602.15 bags = $9596.88
the cost for 600 lbs of PB will be $ 9596.88
