You want to buy a new winter coat that originally costs $115. The coat was marked down to $86.25 so you bought it. What percent
romanna [79]

Answer:

Step-by-step explanation:

The regular price is $62.50.

Explanation:

If the sale price is $50, and the sale is 20% off, that means the $50 represents the other 80% of the regular price—the part that you do pay. So then we ask ourselves, okay, $50 is 80 percent of... what? In math speak, that would be written as

$50(is)80%(of)(regular price)

$50=80% ×           r

Solving this for r, we get

r=$5080%

We remind ourselves that the "percentage" symbol is just a shorthand for "divide this number by 100." The equation becomes

r=$5080/100=$500.8=$62.50

So the regular price is $62.50.

Bonus:

A general formula can be used for any regular price r, any percent discount p, and any sale price s:

     p%off     of  reg.price  is    sale price

(100−p)%×       r        =        s

As long as we know two of the three variables {p,r,s}, we can solve for the third one.

Write a function in terms of t that represents the situation.
AURORKA [14]

The exponential function is given by y = 210000(1.125)^t \\

<h3>exponential function</h3>

An exponential function is in the form:

y=ab^x

Where a is the initial value of y and b is the multiplier factor

Let y represent the population after t years.

Given an initial population of 210000, hence:

  • a = 210000

The population increases by 12.5% each year, hence:

  • b = 100% + 12.5% = 112.5% = 1.125

The exponential function is given by y = 210000(1.125)^t \\

Find a polynomial, which if substituted for M will make the equation an identity: (4c^2–7c^2+6)–M=0
Aleksandr-060686 [28]

Answer:

-3c^2 +6

Step-by-step explanation:

The equation will be an identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combining the c^2 terms.

The contents of parentheses simplify as follows:

... (4c^2 -7c^2 +6) = (c^2(4 -7) +6) = (-3c^2 +6)
