Premium Compound Growth and Depreciation | Maths Codebreaker | Answers Included

PREMIUM RESOURCE - available to purchase; this is not a free download.

Repeated growth and depreciation, including recovering an original amount.

This Premium paid resource contains one complete A4 pupil worksheet with 22 questions and a matching answer page with workings, plus a product-family guide. Pupils solve the maths, match answers to letters in the code grid and decode the hidden words.

Difficulty: Level 7 of 10 within this range (1 is easiest; 10 is most demanding). These levels are a guide to relative challenge, not GCSE grades.

Three questions from this worksheet:
1. A savings account holds £250.00 and earns 5% compound interest each year. Find the balance after 3 years, to the nearest penny.
2. A camera costs £600.00 and depreciates by 15% each year for 3 years. Find the total loss in value in pounds, to 2 d.p.
3. After 3 years earning 10% compound interest per year, an account balance is £2662.00. Find the initial deposit in pounds, to 2 d.p.

Use for focused practice, consolidation, homework or a lesson activity after teaching the method. Print the pupil page for learners and retain the answer page for checking. Follow the rounding and unit instructions on the sheet.
