Question

Isaac sells sandwiches in his shop. He spent a total of £92.65 on sandwiches, including delivery. He then sold: • 10 chicken salad sandwiches at £2.50 each • 15 prawn mayo sandwiches at £3.20 each • 9 egg mayo sandwiches at £1.95 each. Calculate the percentage loss Isaac made for this order.

Answer 1

%age loss = 2.3%

Explanation:

total amount spent = £92.65

sold items are:

10 chicken salad sandwiches = £2.50 each

selling price of 10 chicken salad sandwiches = 10 * 2.50 = £25

15 prawn mayo sandwiches = £3.20 each

selling price of 15 prawn mayo sandwiches = 15 * 3.20 = £48

9 egg mayo sandwiches = £1.95 each

selling price of 9 egg mayo sandwiches = 9 * 1.95 = £17.55

total amount received = £25 + £48 + £17.55

= £90.55

loss = total amount spent - total amount received

= £92.65 - £90.55 = £2.1

%age loss = 2.1/92.65 * 100

= 2.3%
