Below are sample questions representative of the exercises included on this worksheet and related 8.89 Unit Pricing and Comparison Shopping skill assessments:

Problem 1Difficulty: Mastery

Mountain Station sells avocados in two sizes. - Small pack: $7.30 for 1 lb (you use it all) - Bulk pack: $21.63 for 3 lb (about 15% will spoil before you can use it) Which option has the lower cost per usable lb?

ABulk pack

BThey have the same usable unit price

CNot enough information

DSmall pack

Solution & Explanation:Small pack usable amount = 1 → unit cost = $7.30 ÷ 1 = $7.30 per lb. Bulk pack usable amount = 3 × (1 − 15/100) = 2.55 usable lb. Bulk unit cost = $21.63 ÷ 2.55 ≈ $8.48 per usable lb. Choose the smaller usable unit cost.

Problem 2Difficulty: Mastery

Sales tax is 9.0%. You want to buy a calculator. - River Store: regular $70.00, 20% off at checkout, then a $12.00 mail-in rebate - Mountain Mart: $66.00 at checkout, no rebate Which store gives the lower final cost after tax and the rebate? (Assume the rebate is received after purchase and does not reduce sales tax.)

AMountain Mart

BNot enough information

CThey cost the same after rebate and tax

DRiver Store

Solution & Explanation:River Store: sale price = $70.00 × (1 − 20/100) = $56.00. After tax: $56.00 × (1 + 9.0/100) = $61.04. After rebate: $61.04 − $12.00 = $49.04. Mountain Mart: after tax = $66.00 × (1 + 9.0/100) = $71.94. Compare $49.04 vs $71.94 and choose the smaller.
