The sesonal sale on winter wear is 15% off what is the total cost if the original price is 400$

$340

Step-by-step explanation:

Considering 15% off it means customers pay 100-15=85%

Considering that the original price is given as $400 but one only pays 85% of this then the amount payable will be 85% of $400

85% converted to decimal will be 85/100=0.85

Therefore, the amount payable when the offer of 15% exist on the original lrice of $400 is 0.85*400=$340

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

45
