A couch and coffee table cost a total of $1080. The cost of the couch is two times the cost of the coffee table. Find the cost o

Alborosie

Answer:

$720

$360

Step-by-step explanation:

Let the cost of couch be A and that of coffee table be B

Given couch and coffee table cost $1080

That’s

A + B = $1080

Also, the cost of couch A is 2 times the cost of coffeee table B.

That’s

A = 2B

We now have two equations

A + B = 1080

A = 2B

Now ,substitute 2B for A in the first equation .

We have

A + B = 1080

2B + B = 1080

3B = 1080

Divide both sides by 3

3B/3 = 1080/3

B = 360

The coffee table cost $360

Remember A = 2B

Therefore

A = 2 x $360

A = $720

The couch cost $720 while the coffee table cost $360

In a survey of 2,200 people who owned a certain type of car, 1,210 said they would buy that type of car again. What percent of

katrin [286]

Answer:

55%

If 1,210 people would buy that type of car again, they were satisfied with it.

The fraction of people who were satisfied would be $\frac{1210}{2200}$ .

To find a percentage, we need to divide the top of the fraction by the bottom, then multiply by 100.

1210/2200 is equal to 0.55. This is the decimal form of the fraction, but we need the percentage.

0.55 x 100 is equal to 55.

The answer is 55%
