Question

Rosa and Albert receive the same amount of allowance

each week. The table shows what part of their allowance
they each spent on video games and pizza

A: Who spent more or their allowance no video games? Write an inequality to compare the portion spent on video games.

Answer 1

0.4x < 0.5x

Explanation:

Let x = Amount of money Rosa and Albert earn each week

Rosa:

Rosa spends 0.4(x) and 2/5(x) each week on video games and pizza

That equals to :

• 0.4x + 0.4x
• 0.8x

Rosa spends 0.8x, or 80% of her allowance on video games and pizza

Albert

Albert spends 1/2(x) and 0.25(x) each week on video games and pizza

• 0.5x + 0.25x
• 0.75x

Albert spends 0.75x, or 75% of her allowance on video games

Rosa spends 0.4x on video games, and Albert spends 0.5x.

0.4x ≤ 0.5x
