Worked example

How the sheet explains it

The helper printed at the top of each sheet: one solved example and the steps a student follows, before the first question. Every number sentence in it is proven by the same checker as the answer key.

Level 1: Find the saving

A board game costs $46.00. It is 30% off. How much do you save? $13.80

  1. Find 10% first: $46.00 ÷ 10 = $4.60.
  2. 30% is 3 times 10%: 3 × $4.60 = $13.80.
  3. So you save 30% of $46.00, which is $13.80.

Level 2: Find the sale price

A jacket costs $64.00. It is 15% off. Sale price: $54.40

  1. 10% of $64.00 is $6.40, and 5% is half of that: $3.20.
  2. The 15% discount: $6.40 + $3.20 = $9.60.
  3. Sale price: $64.00 − $9.60 = $54.40.

Level 3: Bigger percents: the saving, then the sale price

A backpack is 35% off. The regular price is $84.60. You save $29.61 You pay $54.99

  1. Write 35% as a decimal: 35% = 0.35.
  2. Of means times: you save 0.35 × $84.60 = $29.61.
  3. Sale price: $84.60 − $29.61 = $54.99.
  4. Check: 35% off means you pay 65%, and 0.65 × $84.60 = $54.99.
