Eric and Erica have $5.40 between the two of them. If you double the amount of money Eric has and halve the amount Erica has, then they would have the same amount of money. How much money does Eric have?

Respuesta :

Answer:

$1.08

Step-by-step explanation:

Use a system of equations. Let x represent eric's money and y represent erica's money.

x+y=5.40

2x=1/2y

Let's solve for y in the second equation and substitute it into the first.

Double both sides.

4x=y

Substitute

x+4x=5.40

5x=5.40

Divide by 5

x=$1.08

So eric has $1.08
