At the end of the year, Close made the current year on mark down to make Room for next year models. One particular model had a sticker price of $28,640 when it was new. After being marked down, the price is now $27,208. What What is the percent of decrease in the price of the car

5%.

Step-by-step explanation:

Given data:

Old price = $28,640

New price = $27,208

Solution:

Percentage of decrease

= old price - new price / old price * 100

= $28,640 - $27,208 /. $28,640 * 100

= $1432/$28,640*100

= 0.05*100

= 5%.

The percentage of decrease for the car is 5%.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
