Answer:
- 6 # plastic bricks
- 4 # wooden blocks
Step-by-step explanation:
Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...
10p +5(10-p) = 80
5p = 30 . . . . . . . . . subtract 50
p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.
