Answer:
J. 20
Step-by-step explanation:
Percent increase=increase/original times 100
increase=26-21=5
original=21
so
5/21 times 100=0.23809523809523809523809523809524 times 100=23.809523809523809523809523809524
round
24%
so 24% increase
Answer:
The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
Step-by-step explanation:
Let
x ----> represent the number of home runs Lu hit
y ---> represent the number of home runs Karrine hit
we know that
Together they hit 10 home runs
so
----> equation A
Karrine hit 4 more home runs than half the number of home runs Lu hit
so
---> equation B
substitute equation B in equation A

solve for x


Find the value of y

therefore
The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6
