Grade 7 Math · Tax, Discounts and Simple Interest
Build Grade 7 Math skills with five 10-question practice tests on sales tax, discounts, combined price changes, and simple interest.
These Grade 7 Math practice tests help students apply percentages to purchases and financial situations. Students work with sales tax, discounts, original and final prices, combined discount-and-tax calculations, and simple interest.
Convert each percentage to a decimal before multiplying. Apply a discount to the original price first, then calculate tax on the discounted price when the problem gives both. For simple interest, use I = Prt, where P is the principal, r is the annual rate as a decimal, and t is time in years.
