Answer:

18 weeks

Step-by-step explanation:

Total amount of money saved up to buy the printer is T(w), where w is the number of weeks.

Then T(w) = $100 + ($20/wk)w

Setting this equal to $460, we solve the resulting equation for w to determine the number of weeks it took Hugo to save up $460 total:

$460 = $100 + ($20/wk)w, or

$360 = ($20/wk)w, or

w = $360/($20/wk) = 18 weeks
