Rachel wants to buy a shirt regularly priced at $32. It is on sale for 40% off. Rachel estimates that she will save 2/5 of $30 o
1 answer:
Okay, so first you know that the shirt was priced at $32.
It's on sale for 40%.
40% =
Now we can make a proportion, so set the values in a fraction.
We put 32 on the bottom since it's the total amount.
Divide 100 by 32, so 100÷32=3.2
Now divide the numerator (40) by 3.2, so 40÷3.2=12.5
That means the new cost of the shirt is $12.50 so the new amount will be more than 12 dollars.
Hope that helped :)

Step-by-step explanation:
Given that the function s(t) represents the position of an object at time t moving along a line. Suppose s(2)=150 and s(5)=237.
To find average velocity of the object over the interval of time [1,3]
We know that derivative of s is velocity and antiderivative of velocity is position vector .
Since moving along a line equation of s is
use two point formula
gives the position at time t.
Average velocity in interval (1,3)
=
