Apples cost 14 cents each and grapefruit cost 25 cents each. If I buy 2 more apples than grapefruit the total cost is $3.40. How many apples do I buy?

Respuesta :

Answer:

10

Step-by-step explanation:

let a = amount of apple

let g = amount of grapefruit

14a+25g=340

a+g=2a-2

-a     -a

g=a-2

plug this into your first equation

14a+25(a-2)=340

14a+25a-50=340

              +50  +50

39a=390

a=10

you have 10 apples
