At a local department store, cardigans have been reduced to $15. This price is at 50% of the original price for cardigans. Given this, what was the original price of the cardigans? Round your answer to the nearest whole number if necessary.

$30

Step-by-step explanation:

To start off, we know that cardigans have been reduced to a price of $15. This price is 50% of the original price. We also know that 50% is another way of saying 1/2. This means that the price of the cardigans is half of what it used to be.

To solve, simply multiply $15 by 2 as shown below:

$15 x 2 = $30

The original price of the cardigans was $30.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
