Question

S. A camera stores 306 photographs. A machine charges 11p per print for the photographs. Estimate the cost to print out all the photographs.

​

Answer 1

£35

Explanation:

Estimate 306 × 11p

300 × 10 = 3000

11 is 10% more than 10, change estimate to 3300.

306 is a bit more than 300, so estimate is approx. 3500.

Answer: £35
