Question

Mitchell is a plumber who has a bill for $278.50 from the local hardware store. Mitchell is given a 10% trade discount, then a further 5% if the bill is paid in cash. Calculate the amount that Mitchell must pay in cash.(Remember to round to the nearest 5 cents)

Answer 1

amount after 1st and 2nd discounts=278(98/100)(95/100)=259.28
amount after 1st and 2nd discounts formula is p*(1-1ist discount)((1-2ist discount) %
