Question

You need to buy 30 pounds of hamburger and 15 packages of buns for a staff appreciation picnic.you have 2 options for hamburger and 2 options for buns shown below. In addition you have a 10%- off coupon that can be used on either the hamburger or the buns, but not both, after any other discounts are applied. What is your best cost, including tax of 5% of the purchase price after all discounts, rounded to the nearest 0.01

Answer 1

Solution :-

We have to determine the best cost after all discounts and tax.

Hamburger:

1 RS of Open Acres = RS 2.39

30 Rs of Open Acres

=> 30 × 2.39= 71.7 RS

=> 10/100 ×71.7

Total cost of 30 Rs of Open Acres Hamburgers = 71.7 - 7.17

=RS 64.53

Buns:

1 packet of Burly buns = RS 1.93

15 packets of Burly buns = 15× 1.93

=28.95 RS

5% off on 15 packets of Burly buns = 5% of RS 28.95

Now, according to the question, a 10%-off coupon that can be used on either the hamburger or the buns, but not both, after any other discounts are applied.

Let us apply 10% off applied on Hamburgers:

10% of RS 64.53

=> 10/100 × 64.53 => 6.453 RS

=> Now, total cost of hamburgers after all the discounts = RS 64.53-rs 6.453

= RS 58.077

And total cost of Buns after all the discounts = RS 27.50

Total price of hamburgers and buns = RS 58.077 + RS 27.50

= RS 85.577

5% tax applied on total price of hamburgers and buns = 5% of RS 85.577

= RS 4.28

Best cost on the purchase of hamburgers and buns = RS 85.577 + RS 4.28

= RS 89.857

Rounding to the nearest hundredth

best cost on purchase of 30 Rs of hamburgers and 15 packets of buns after all discounts and tax = RS 89.86
