Helen [10]

The Original price of the meal was $12.16.

Discount Percent is defined as the discount given on the product per hundred .

For Example . if there is 10% discount on a price of $100.

The final amount will be $90.

Final amount paid by Fiona = $8.25

percentage discount = 10%

Let the original amount be x.

According to the question ;

x - 10% of x = 8.25

x-\frac{10}{100} *x=8.25\\ \\ \frac{100x-10x}{100} =8.25\\ \\ \frac{90x}{100} =8.25\\ \\ x=\frac{8.25*100}{90}\\ \\ x=\frac{825}{90}  \\ \\ x=9.16

Since Fiona also had a discount coupon of  $3.

The original amount will be $9.16+$3=$12.16.

Therefore , The original price of the meal was $12.16.

Evaluate the following expression:
Maurinko [17]

Answer:

1

Step-by-step explanation:

{6}^{2} - 7(8 + 6 -  {3}^{2})

Using BODMAS we'll have to solve what is in the bracket first

=  {6}^{2}  - 7(14 - 9) \\  =  {6}^{2}  - 7(5) \\

Multply -7 by 5 still using the rule of BODMAS

=  {6}^{2}  - 35 \\  = 36 - 35 \\  = 1
