Answer:

  • the number of 1 bed-room apartment: 5
  • the number of 2 bed-room apartment: 7

Step-by-step explanation:

  • Let x is the number of 1 bed-room apartment
  • Let y is the number of 2 bed-room apartment

Given the information:

  • The total number of  apartments: 12
  • rent for one bedroom apartment: $360
  • rent for two bedroom apartment: $450
  • total monthly rental is $4,950

Hence, we can form two equations:

x + y =12 <=> x = 12-y (1)

360x + 450y = 4950 (2)

Let substitute (1) into (2), we have:

360(12-y) + 450y = 4950

<=> 4320 - 360y + 450y = 4950

<=> 90y = 630

<=> y = 7

=> x = 12-7 = 5

So, we have:

  • the number of 1 bed-room apartment: 5
  • the number of 2 bed-room apartment: 7

Hope it will find you well

Write two different expressions to represent the sale price of a fishing pole, f, after a 20% discount.
Rom4ik [11]

Answer:

When we have a discount of X% of the original price, the new price is calculated as:

New price = (original price) - (original price)*(X%/100%)

In our case, let's define:

P = original price of the fishing pole

f = price of the fishing pole after the discount

X% = 20%

Then the equation for the price of the fishing pole is:

f = P - P*(20%/100%) = P - P*0.2 = P*(1 - 0.2) = P*0.8

f = 0.8*P

This means that the price after the discount is 0.8 times the original price.

a poll shows that 64% of americans personally worry a great deal about federal spending and the budget deficit.
marysya [2.9K]

In the research, it should be noted that this is a Proportion, because worry or not worry is categorical

<h3>What is a proportion?</h3>

A population proportion is the percentage of the population that possesses a particular trait.

For illustration, suppose there are 1,000 people in the population and 237 of them have blue eyes. There are 237 blue eyed people out of every 1,000 people, or 237/1000.

Therefore, it should be noted that this is a Proportion, because worry or not worry is categorical.

For breakfast, Randy had two Egg McMuffins and a hash brown, to taling 750 calories . Jack only had on e Egg McMuffin and a hash
Delvig [45]
Let us assign variables.
Let x = egg mcmuffins
Let y = hash brown

Randy had:
2x + y = 750

Jack had
x + y = 450

Using systems of linear equation, we can get the value for x and y by elimination. Subtract the equations.
2x + y = 750
x + y = 450
--------------
x = 300

Get y
x + y = 450
300 + y = 450
y = 150.

So there are 300 calories for McMuffins and 150 calories for hash brown.
