The better value is Quick Clean. Quick Clean is $0.03 cheaper per roll of paper towel.
To get there -
1. divide your price by your amount to get the unit price for one of the item (in this case paper towels)
2. do the same for your other price.
3. make sure you are keeping things labeled and separate so you know what means what :)
4. compare the two prices and decide which one answers the question you are being asked (again in this case which is a better deal)
Hope that helps!
DR/dt= -5inM-¹
dH/dt = 5inM-¹
recall V=πr²h
dV/dr = 2πrh
dV/dh= πr²
dV/dt = ½{ (dH/dt • dV/dH) + (dV/dr • dr/dt)}
dV/dt = ½{ ( 5×πr²) + (2πrh×-5)}
dV/dt = ½{ 5πr² -10πrh}
= ½{ 80π - 120π}
= -20π inM-¹
Take a common factor of cos(x)
then by zero multplication rules

and
It's says p-1 is factor to the equation, so that means when
p=1, the remeinder of the equation is zero. Mening:
p4 + p2 + p - k = 0
plug p=1 into the equation and find k
1^4 + 1^2 + 1 - k = 0
1 + 1 + 1 - k = 0
k = 3
A) just exchange the (y) for [f(x)]
