Answer:
50(20 + t) pounds
Step-by-step explanation:
Let the weight of each fairly small rock be represented by t pounds.
Each brick weighs 10 pounds, then:
the weight of 100 bricks = 100 x 10
= 1 000 pounds
Each rock weighs t pounds, then:
the weight of 50 rocks = 50 x t
= 50t pounds
Therefore, the total weight of what Harvey lifted = total weight of bricks + total weight of rocks
= 1 000 + 50t
= 50(20 + t) pounds
