Question

hugo received $100 for his bithday. He then saved $20 per week until he had a total of $460 to buy a printer. Use the equation to show how many weeks it took him to save the money.

Answer 1

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:

$y=100+20x$

This equation represents the total money y Hugo has after x weeks.

The printer cost $460. Thus, set y to $460:

$460=100+20x$

Solve for x.

Subtract 100 from both sides:

$360=20x$

Divide both sides by 20:

$x=18$

Therefore, it took Hugo 18 weeks to save up $460.
