D.

Answer:10

Step-by-step explanation:

ok they are 18 apples

and they ate them

one ate two more thatn the other one

so we can say that one of them is x (charles)

and the one who ate two more is x+2 (lisa)

so we get this

x+x+2=18

2x+2=18

2x+18-2

2x=16

x=8

so charles ate 8

and lisa 10 (8+2)
