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:
This equation represents the total money y Hugo has after x weeks.
The printer cost $460. Thus, set y to $460:
Solve for x.
Subtract 100 from both sides:
Divide both sides by 20:
Therefore, it took Hugo 18 weeks to save up $460.
Answer:
B, D
Step-by-step explanation:
Any inequality that does not include the "or equal to" case will be graphed with a dashed line.
<h3>Application</h3>The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).
The inequalities that will be graphed with a dashed line are ...
