1- show that f(t)=t^3+t+6 is of exponential order

Hello!

Let's do this step by step!

#1

"Reducing" means to make something smaller, like a discount. So we are reducing the price of the dress by 20%. This means we must first find what 20% of the dress's price is and then subtract that from the price.

#2

36.80 * 20% = 7.36

So, 20% of 36.80 is 7.36. Subtract that: 

#3

36.80 - 7.36 = 29.44

 

The sale price of the dress is $29.44. 

Good day!
