Question

Eduardo had 16 more stamps than Carson. 1/2 of Carsons stamps were equal to 1/4 of eduardos stamps.

How many stamps did Eduardo have?

After Eduardo gave some of his stamps away, he had 3/8 as many stamps as Carson.

How many stamps did Eduardo give away?

Answer 1

Let E and C be the number of stamps Eduardo and Carson had.

E=C+16. C/2=E/4, so multiplying through by 4: 2C=E.

Now put E=2C in the other equation: 2C=C+16, so C=16 and E=C+16=32.

Eduardo gives x stamps away, so now he has 32-x stamps. 32-x=3/8C=3/8*16=6 stamps. 32-x=6 so x=32-6=26. Eduardo gave 26 stamps away.
