Answer: It'll take Chris 9 weeks to have enough money to buy the new bike. w = 9
Step-by-step 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
[tex]\frac{90}{10}[/tex] = [tex]\frac{10w}{10}[/tex]
[tex]\frac{90}{10}[/tex] = w
9 = w
Answer: w = 9
