The total price of each burger is set at $2 per patty. Let T represent the total price a randomly chosen customer pays for their burger. Find the mean of T

Answers

Answer:

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

Step-by-step explanation:

Let's find out the mean of T (total price a randomly chosen customer pays for their burger), this way:

Mean of T = 0.4 * $ 2 + 0.5 * $ 4 + 0.1 * $ 6

Mean of T = 0.8 + 2 + 0.6

Mean of T = US$ 3.40

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

A proposed change in income tax suggests charging 25% on a person's income up to $42,000 and then 40% on any income above that. If a person has an income of $68,000, what will their income tax be under the proposal? Round your answer to the nearest dollar.

Answers

Answer:

$20,900

Step-by-step explanation:

-The income tax is 25% on first $42,000 and 40% on all amounts greater than $42000

#Tax on first $42,000:

$Tax=Tax \ Rate* Income\n\n=0.25* 42000\n\n=10500$

#Tax on the income balance will be:

$Balance=68000-42000=26000\n\nTax=0.4* 26000\n\n=10400$

Total income tax=10400+10500=$20,900

Hence, the proposed income tax will be $20,900

Another word problem. Please show how you get the answer. A particular number was divided by 5 and then 12 was taken from that quotient. Finally, this difference was multiplied by 5. Given the product was -55, what was the number?

Answers

The number would be 5. 5 divided by 5 equals 1. Then 1-12 would be -11 and then you do -11 times 5 which gives you -55!
