Every month we will give you a math/statistics brain teaser that lets you test your
knowledge with a fun problem.
This Month's Challenge: How Many Games?
Brothers Matt and Tyler love playing video games together. They decided if they split their chore money every month, they can afford more video games to play together.
Matt cuts the grass every other week for $20, while Tyler does the dishes every day for $10 a week.
Matt and Tyler have two options for buying video games: they could buy brand new games for $60 each, or retro games for $20 each.
How many games per month can Matt and Tyler afford for brand new games or for retro games?
Click here for answer!
Step 1: Figure out how much Matt and Tyler make per month.
If Matt does the lawn every other week for $20 per cut, Matt gets paid twice a month.
$20 * 2 = $40
If Tyler does the dishes for $10 per week, that means Tyler gets paid 4 times a month.
$10 * 4 = $40
So adding their totals together...$40 + $40 = $80 per month.
Step 2: Take their monthly total and figure out how many games they can afford.
Matt and Tyler can afford:
1. Brand new game: $60 each, so the earned $80 - $60 = $20 left over, meaning they can get 1 game and save $20 towards next month.
2. Retro game: $20 each, so $20 * 4 = exactly $80, meaning they can afford 4 retro games.
