What is the cost of each item? What is the subtotal? What is the tax? What is the total paid? Shoes: $49.99 (normally) they are
prisoha [69]

Answer:

Cost of shoes = $37.4925

Cost of jacket = $92.4533

Tax = $9.81

Total paid = $144.2458

Step-by-step explanation:

Normal price of shoes = $49.99

Discount = 25%

Discounted price:

\$49.99 - \$49.99\times \dfrac{25}{100} = \$37.4925

Normal price of jacket = $137.99

Discount = 33%

Discounted price:

\$137.99 - \$137.99\times \dfrac{33}{100} = \$92.4533

Price of pack of cookies = $4.49

No discount on cookies as per question statement.

Total amount without tax = $37.4925 + $92.4533 + $4.49 = $134.4358

Sales Tax = 7.3% of total amount without tax = 7.3% \times $134.4358 = $9.81

Total paid = $134.4358 + $9.81 = <em>$144.2458</em>

Which of the following is a function?
seropon [69]

Answer:

C

Step-by-step explanation:

For any of the functions described above, the only way any of those could be functions is that there has to be a difference value for each x, unless it is the same x-value. If the x is mentioned twice, that is fine, as long as the y point is also the same. If it is different, it is not a function.

Help would be appreciated

Hello!

First you have to find the area of the space

300 * 500 = 150000

Next you have to find the space 5 people take up

5 * 5 = 25

Divide these two numbers

150000 / 25 = 6000

multiply this by the amount of people take up that space

6000 * 5 = 30000

The answer is D)30,000 people

Hope this helps!
