A jacket is on sale for 40% off .The sale price is $90.00.What is the original amount of the jacket
34kurt
Set up a proportion
90/x = 60/100
60x = 9000
x = 150

if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%

hope this helps!

Second time asking plz help. Linear or exponential. plz help me :(​
7nadin3 [17]

Answer:

Exponential

Step-by-step explanation:

The change isn't constant for the volume, so it must be exponential.

Using quadratic regression, the equation is:

y=\frac{19}{63}x^{2}-\frac{968}{105}x+\frac{3312}{35}
