The answer should be C. 8 because two times the amount that Charles ate which is 4 equals 8 and 4+8=12
Answer:
8
Step-by-step explanation:
let x represent the number of of watermelon slices Charles ate.
2x+x=12
x+x+x=12
3x=12
3x/3=12/3
x=4
Charles ate 4 watermelon slices
If Lisa ate twice the amount Charles ate, that would mean she ate 8.
