Answer:

P=2(l)+2(w)

90=2(4w-5)+2(w)

90= (8w-10)+2w

90=10w-10

10+90=10w-10+10

100=10w

w=10

90=2(4[10]-5)+2(10)

90=2(40-5)+2(10)

90=2(35)+20

90=70+20

90=90

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.

mixas84 [53]

Answer:

The percentage of the bags of the potato chips that are not cheddar-flavored is 25%. This is because there are 10 bags that are not cheddar-flavored and this divided by 40 bags, which is the total bags of the potato chips multiply by 100% gives 25%

Step-by-step explanation:

If there are 40 bags of potato chips and 30 are cheddar flavored, Then

40 - 30 = 10 bags are not cheddar flavored

Since the total bags is 40,

percentage potato chips that are not cheddar-flavored = 10/40 × 100%

= 25%
