A store makes 20% profit on the total price of all the items they sell.

let t represent the total price of all items sold in dollars, and let p represent the profit in dollars.

1) WRITE AN EQUATION TO REPRESENT THE RELATIONSHIP BETWEEN THESE VARIABLES:

Pls help! I don’t understand!! :/

Answers

Answer:

p=1/5t

Step-by-step explanation:

Since t is 100% of the items sold and p is 20% of that, the profit, p is 20% of t, or 1/5t.

Answer:

p = t(0.2)

Step-by-step explanation:

The profit is 20% of the total price. So if you multiply the total price by 0.2, you will get 20% of the total price which is the profit.

The dimensions of a triangular prism are shown.
What is the surface area of the triangular prism?


A.20.5 square inches

B.29 square inches

C.32 square inches

D.14.5 square inches

Answers

Answer:

C

Step-by-step explanation:

To find surface area you find all the areas of the sides and add them up. We can start by setting up our equations.

A = L x W

For both the sides ——> 2(5 x 0.5) = 5

For both the triangle parts ——> bh/2 ———> (4 x 6)/2 times 2 = 24

For the bottom part ——> 6 x 0.5 = 3

Now to add everything up: 24 + 3 + 5 = 32

The answer should be C.

Solve: 2x + 3y = 1
y = -23 +11

Answers

Answer:

x = 18.5

y = -12

Step-by-step explanation:

First, solve y:

y = -23 + 11

y = -12

Then, solve the main problem:

2x + 3y = 1

(Substitute y)

2x + -36 = 1

2x - 36 = 1

2x = 1 + 36 = 37

x = 37 / 2

x = 18.5

Two planes travel at a constant speed. Plane A travels 2,800 miles in 5 hours. Plane B travels 3,885 miles in 7 hours.

1. Which plane is faster?

Answers

Answer: First.

Step-by-step explanation:

Let's find the speed of the first airplane:

2800 ÷ 5 = 560 (miles per hour)

Let's find the speed of the second plane:

3885 ÷ 7 = 555 (miles per hour)

Thus, the first plane flies faster than the second.

The first plane is faster.


The first plane travels at 560 miles per hour. The comparisons are 2 hours apart. Add 560 2 times to 2800 and you get 3,920 which is greater than 3,885, the original number of MPH for the second plane.


Meaning the first plane is faster.

Answers

Answer:

885.45

Step-by-step explanation:

Testuo monthly payments will be around 885$

What is Interest

It is a fee paid for borrowing money or other assets.

• the amount borrowed is called the principal.

•  the interest is expressed as a percentage rate of the principal

for a given time interval.

It is given that

Value of the car = $32000

Time period of loan repayment = 36 months

T = 3 years

Rate of Interest = 6.71%

10% down amount from 32000  =  3200 $

So the amount he is putting for finance = 32000 - (0.1 × 32000)

                 

                                               = $28800

Rate of interest can be calculated from

I = P x R x T

I = Interest, P = Principle, R = Rate, T = Time

= (6.71 * 28800 * 3)/(100*12)

= $ 483.12

This is total interest for an year

In one month, rate of interest

= 483.12/12

 = $40.26

The principal amount that will be payable per month

= 28800/36

= $800

                                                           

Total amount payable will be

= $ ( 800 + 40.26 )

= $840

                                   

Hence, we can conclude, Tetsuo needs to pay $840.26 as monthly installments, so in the options given it is 885$
