Step-by-step explanation:

Answer 2
Answer:

Answer:

$36

Step-by-step explanation:

Since 30% = 30/100 then we can transform it into a decimal:

30%=0.30

Now if we multiply 120•0.30, we will get how much we saved.

$36, we saved $36.

Bonus information:

If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.

Which of the following decimals has the least value 0.3 0.029 0.003 0.01

Answers

Answer:

The correct option is 3.

Step-by-step explanation:

The given numbers are

0.3, 0.029, 0.003, 0.01

If we compare two or more numbers then the extreme left are compared. The one having the greater extreme left digit will be greater.

Compare first two numbers.

0.3 > 0.029

Now compare third number with smaller value.

0.029 > 0.003

Now compare fourth number with smaller value.

0.01 > 0.003

The number 0.003 is smaller than  0.3, 0.029 and 0.01.

Since 0.003 is least value. Therefore the correct option is 3.

Look at it this way:

0.300
0.029
0.003
0.010

The decimal 0.003 has the least value because .300, .029, and .010 are greater than 0.03

The constant of proportionality(k) between a yard and a foot is 0.33.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

The variable feet and yards are in direct proportion.

Let,

yard = k(feet).

1 = 3k

k = 1/3 = 0.33.

We can conclude that -

  • The percentage by which the selling price will decrease is 16%. The price will have to increase by 16% to return back to the original price.
  • The price will have to increase by 16% to return back to the original price.

What is Selling price?

The price at which a specific commodity is sold is known as the selling price.

Given is that the selling price of a house dropped from $250,000 to $210,000 over a period of 5 years.

A -

The percentage by which the selling price will decrease is -

%decrease = (250000 - 210000)/250000  x  100

%decrease = 40000/250000  x  100

%decrease = 4/25 x 100

%decrease = 4 x 4

%decrease = 16%

B -

The price will have to increase by 16% to return back to the original price.

Therefore, we can conclude that -

  • The percentage by which the selling price will decrease is 16%. The price will have to increase by 16% to return back to the original price.
  • The price will have to increase by 16% to return back to the original price.

carol is excited to get a new kitten from the animal shelter. the kitten had an $299 adoption fee. carol had $50 off coupon for the adoption and will also have to pay $20 per month for food and supplies. how longg will it take for carol to spend $250​

Answers

Answer:

1 month

Step-by-step explanation:

249 is the amount she spends for buying the kitten, (299-50=249) which she only has to pay once.

20 is the amount she has to spend every month, the rate of change.

The problem can be modeled with the general equation:

y = 20x + 249

In this equation, x the the time in months and y is the amount of money spent.

Substitute 250 for y.

y = 20x + 249

250 = 20x + 249    <= isolate x to get the number of months

1 = 20x

x = 1/20

Carol will only spent money every month, not for 1/20 of a month.

It will only take Carol 1 month to spent $250.

Check answer:

Substitute x for 1

y = 20x + 249

y = 20(1) + 249

y = 269

269 is more than 250 already.
