Pedro had 1482 hits and Riley had 1200 hits.
Step-by-step explanation:
Given,
Number of base hits = 2682
Let,
Number of Pedro's hits = x
Number of Riley's hits = y
According to given statement;
x+y=2682 Eqn 1
x = y+282 Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 2

Putting y=1200 in Eqn 2

Pedro had 1482 hits and Riley had 1200 hits.
