Answer:

Step-by-step explanation:

A 36% discount means the selling price is (100-36)% = 64% of the original price.

$272 = 64% of x = 0.64·x

x = $272/0.64 = $425

Help me... :/<br><br> Find the measure of each exterior angle of a regular 45-gon.

GuDViN [60]

Answer:

7740° / 45

Step-by-step explanation:

The sum of the interior angles is given by this formula: (n - 2) * 180°. So a regular 45-gon would have interior angles that add up to: (45 - 2) * 180°. = 43 * 180°. = 7740°. Now divide that by the 45 angles to find the measure of one interior angle

hope that helped :(

Sam's total expenses last month were $1840. What was his total variable cost for last

likoan [24]

Answer:

$1500

Step-by-step explanation:

It is given that

Rent = $100

Groceries and drinks = $1000

Insurance premiums = $10

Loan interest payment =$30

Clothes = $200

Utilities = $300

Home security fee = $200

Fixed cost are costs that does not vary and variable cost are costs that vary with goods and services.

In the given problem, rent , insurance premiums, loans interest payment ad home security fee are fixed cost.

Groceries and drinks, clothes and utilities are variable cost.

So, total variable cost for last month is

$\text{Total variable cost}=\$1000+\$200+\$300=\$1500$

Therefore, total variable cost for last month is $1500.
