In this section we look at problems in practical contexts which can be solved using arithmetic.
(1) Sarah buys 8 ice creams costing 95p each. How much does she spend?
The answer is 8 × 95p = 760p = £7.60
(2) It takes Paul 22 minutes to wash a car. How many cars can he wash in 1 hour and 50 minutes?
We need to find out how many times 22 minutes goes into 1 hour and 50 minutes.
