Question

Leo is a barber.

He charges £5 for a haircut.
He charges 10% extra for hair gel.
One day 25 customers have a haircut.
16 of these ask for hair gel.
Work out the total amount that Leo charges his customers that day.

Answer 1

10% extra of £5 = 110% of £5 = 1.1 x £5 = £5.50

25 x £5 = £125
16 x £5.50 = £88

£125 + £88=£213

Answer: £213 (I think)
