The total weight of the boxes of cheddar cheese was 330 pounds.
Sample explanation:
Let c be the number of boxes of cheddar cheese.
Weight per box (lb) ×
Number of boxes =
T otal weight (lb)
Cheddar

c
3c
Swiss
2
c − 20
2(c − 20)
Since the total weight of the shipment was 510 lb:
510 = 3c + 2(c − 20)
510 = 3c + 2c − 40
510 = 5c − 40
550 = 5c
110 = c
There were 110 boxes of cheddar cheese in the shipment.
Since each box of cheddar cheese weighs 3 lb, the total weight of the boxes of cheddar cheese was 110
boxes × 3 lb/box = 330 lb.
