Question

Chris is saving money to buy a new bike that costs $189. He has saved $99 so far. He plans on saving $10 each week. In how many weeks will Chris have enough money to buy the new bike?

Answer 1

he will have the money in 9 weeks

99+10+10+10+10+10+10+10+10+10=189

Answer 2

Answer: It'll take Chris 9 weeks to have enough money to buy the new bike. w = 9

Explanation:

Hey there! If you have any questions please feel free to ask them in the comments.

We can write down the formula for this problem as:

$189 = $99 + $10w

$189 is the total amount of money Chris needs, and $99 is the amount of money Chris already has. $10w would be $10 per week in which Chris will have enough money to buy the new bike.

Steps: Solve for W

$189 - $99 = $99 - $99 + $10w

$90 = 0 + $10w

$90 = $10w

`(90)/(10)` =
`(10w)/(10)`

`(90)/(10)` = w

9 = w

Answer: w = 9
