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)

-4

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
