Jolie purchased a concert ticket on a web site. The original price of the ticket was $110. She used a coupon
code to receive a 15% discount. The web site applied a 10% service fee to the discounted price. Jolie's ticket
was less than the original price by what percent?

Answers

Answer:

I got 7%

Step-by-step explanation:

110 x .15 = 16.5

110-16.5=93.5

93.5 x .10 = 9.35

93.5 + 9.35= $102.82

Thats the discount price

110 - 102.82 + 7.18

7.18/102 = .0698

.0698 x 100 = 6.98

7%

the ratio of pink starburst to yellow starbursts in kels bag 25% What precept of the whole bag contains pink Starburst

Answers

Answer:

Pink Starburst occupies 20% of the total bag space

Step-by-step explanation:

Given

Ratio of pink (P) starburst to yellow (Y) starbursts [tex]= 0.25[/tex]

Mathematically, it can be written as

[tex]\frac{P}{Y} = 0.25\\Y = \frac{P}{0.25} \\Y = 4P[/tex]

Then the % space taken by pink startburt is equal

[tex]\frac{P}{4P + P} \\= \frac{P}{5P}\\= \frac{1}{5}\\= 0.2[/tex]

Hence, Pink Starburst occupies 20% of the total bag space

A balloon is floating above a lake and a sunken canoe is below the surface of the lake. The balloon's vertical position is 12 meters and the canoe's is -4.8 meters. The equation 12 + d = -4.8 represents this situation.

What is the value of the variable in this equation?

Answers

7.2 because you just add the -4.8 to cancel out the -4.8 on the right side. and you get 7.2
The distance between the ballon and canoe is 16.8 meters. So -12+d=4.8

If the cost of an item with VAT is Rs 1,356 and without VAT is Rs 1,200, find the VAT?​

Answers

Given:

Cost of an item with VAT = Rs 1,356

Cost of that item without VAT = Rs 1,200.

To find:

The VAT.

Solution:

We have,

Cost of an item with VAT = Rs 1,356

Cost of that item without VAT = Rs 1,200.

We know that,

VAT = Cost of an item with VAT - Cost of that item without VAT

       = 1356 - 1200

       = 156

Therefore, the value of VAT is $156.
