U have the to use the formula
y2-y1/x2-x1
that will get u the slope
-10-8 = -18
-9-1= -10
this give u 18/10 which can be simplified to 9/5
so the slope is 9/5
hope this helps!
Taylor can have 12 guests come.
375 - 250 = 125 / 10 = 12.5 but since you cannot have half a person the answer is 12
I hope this helps :)
$4 is the original price of the jar consisting of peanut butter so therefor it = 100%. It's for sale at $3.60, so we divide $4 by 100% so we get the percentage for each cent and then we times it by 3.60 to get the percentage for $3.60 which is 90%. Now we subtract 90% from 100% to get the discounted percentage for 40cents :)
