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

=

= w

9 = w

w = 9
