Answer :
Answer:
18 weeks
Step-by-step explanation:
So, Hugo received $100 for his birthday.
He saved $20 per week. Let x denote the weeks that passed. Therefore:
[tex]y=100+20x[/tex]
This equation represents the total money y Hugo has after x weeks.
The printer cost $460. Thus, set y to $460:
[tex]460=100+20x[/tex]
Solve for x.
Subtract 100 from both sides:
[tex]360=20x[/tex]
Divide both sides by 20:
[tex]x=18[/tex]
Therefore, it took Hugo 18 weeks to save up $460.
