Ateacher buys a school sweatshirt at 35% off the original cost. if the original cost of the sweatshirt was $40.00, what is the sale price? can you also explain how you got the answer ?

The sale price is 26$ 

First you have to find the difference in price (which for this problem is 14$)
Second you subtract the difference in price from the original cost 
Third what you get from subtracting is your new sale price 

(Here's the math)

40-14=26

Hello!
Formula : original price - ( original price · percent)
 40 - ( 40 · 0.35)
  40 - 14
      26
The sales price is $26 because when finding the sales price you have to add the original price to the product of the percent and the original. The original price would be decreased since this is 35% OFF the original price.

Hope this helps! :D

y=-x+1

Step-by-step explanation:

to get this you use the point-slope formula

y-y1=m(x-x1) - plug in the coordinates and find the slope

y--3=-1(x-4) - change the sign and solve the parentheses

y+3=-x+4 - subtract 3 from both sides to get y by itself

y=-x+1
