Answer:
Step-by-step explanation:
If the jacket was discounted at 25%, that means that you get 25% off, right? What it also means is that you are still paying 75%. To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):
290(.75) = 217.50
That's the price of the jacket when it is 25% off the original price. If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%. To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):
217.50(.90) = 195.75
That's what she paid in the end for the jacket (i guess not counting tax...?)
When it gets to zero or the intercept
factor
x=4(t^2-8t+9)
x=(4)(t-9)(t+1)
set to zero
t-9=0
t=9
t+1=0
t=-1, false, time cannot be negative
at t=9 seconds
It costs $100 to start a shop. To make the items that you are going to sell, it costs $5 each.
