Rosa, 0.4 2/5. Albert, 1/2 0.25

Who spent more of their allowance on video games? Write an inequality to compare the portion spent on video games

1/2 x > 0.4x

where Robert's spending is greater than Rosa's spending.

Allowance of Rosa = Allowance of Robert

let x = allowance

Rosa : video games = 0.4 (x); pizza = 2/5 (x)

Robert : video games = 1/2 (x); pizza = 0.25 (x)

let us assume that their allowance is 100 each week. so, x = 100

Rosa : video games = 0.40 (100) = 40

pizza 2/5 (100) = 200/5 = 40

total spending: 40 + 40 = 80

Robert : video games = 1/2 (100) = 50

pizza 0.25 (100) = 25

total spending: 50 + 25 = 75

Spending on video games

Rosa = 40

Robert = 50

Robert spent more of his allowance on video games than Rosa.

1/2 x > 0.4x
