Demand for your tie-dyed T-shirts is given by the formula q = 510 − 90p0.5 where q is the number of T-shirts you can sell each m

telo118 [61]

Answer:

The demand will drop approximately 23 T-shirt per month.

Step-by-step explanation:

Consider the provided formula.

$q = 510-90p^{0.5}$

You currently sell T-shirts for $15 each and you raise your price by $2 per month,

That means p=$15 and $\frac{dp}{dt}=2$

We need to find how fast demand will drop.

So differentiate the above function with respect to time.

$\frac{dq}{dt} =0-45p^{0.5-1}\frac{dp}{dt}$

$\frac{dq}{dt} =-45p^{-0.5}\frac{dp}{dt}$

Substitute the respective values as shown:

$\frac{dq}{dt} =-45(15)^{-0.5}(2)$

$\frac{dq}{dt} \approx-23.24$

Hence, the demand will drop approximately 23 T-shirt per month.

HELP I give big brain! See attachment

Answer:

Step-by-step explanation:

Here is the full steps:

Distribute

-7(x+10)=7(5-x)

-7x-70=7(5-x)

Distribute

-7x-70 = 35-7x → Answer for the attachment "35"

Add 70 to both sides of the equation

-7x-70+70=-7x+35+70

Simplify

-7x=-7x+105

Add 7x to both sides of the equation

-7x+7x=-7x+105+7x

0 = 105
