This question asks us to estimate the amount of money Paul gave to Charity.
- To work out an estimate we must start by rounding the numbers we are given to 1 significant figure and the
Starting with 19.95 --> this rounds to 20 and 395 rounds to 400.
- Then we have to multiply these numbers together:
20 x 400 = 8000
3. Finally subtract 6000 from our estimate
8000-6000=2000
The answer is 2000.
