Tim would like to buy a video game that costs $27. He has not saved any money. His parents are willing to pay him $3 for every 2 chores, but will also pay him for completing single chores.

Tim would have to do 18 chores (2 chores 9 times or 1 chore 18 times) to be able to buy the video game.

Step-by-step explanation:

Step 1; Tim's parents will give him $3 for every two chores. This equals $1.50 for a single chore. He wants to save up $27 so that he can buy the video games he wants.

Step 2; The number of times he has to do the chores to be able to but the video game is a division between the money he wants to save up by the money he gets for the chores.

Number of 2 chores he needs to do = Amount of money he wants to save up / money he gets for doing two chores

= $27 / $3 = 9 times.

Number of single chores he has to do = Amount of money he wants to save up / money he gets for doing two chores

$27 / $1.50 = 18 times
