Can I use this percent word problems worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade percents, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What kinds of percent problems are on these sheets?
⌄
They cover discounts, sales tax, tips, markups and markdowns, percent increase and decrease, and simple interest. Each sheet focuses on a few of these in real situations.
How do you find the price before tax?
⌄
Write an equation and divide the total by 1 plus the tax rate as a decimal. Find the Tax Rate or Original Price has students do this for totals such as $26.46 with 8% tax.
How do you find the interest for a number of months?
⌄
Change the months to years, then use I = Prt. Simple Interest With Partial Years uses 9 months for $800 at 4.5% as its first problem.
