Jenny catches a taxi from the supermarket to her house. The taxi firm charges £3.00 standing charge, plus 50p per mile.

How much will it cost Jenny to travel 8 miles?

When looking at this, you should leave the £3.00 standing order (S. O) until the end, and focus on the other numbers.

50p (per mile) x 8 (miles) = £4.00.

£4.00 + £3.00 (S. O) = £7.00.

Therefore, whole journey will cost Jenny £7.00.
