The cost to print digital photos at a local store is

snow_tiger [21]

<h2>The cost is same for both the options if we purchase 27 photos</h2>

Step-by-step explanation:

Cost of a photo at a local store is $0.25 per photo. This cost can be modeled to be linear in number of photos as $C_{1}(x)=0.25x$ .

Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as $C_{2}(x)=2.70+0.15x$ .

Let us assume both costs are the same if we purchase $n$ photos.

So, $C_{1}(n)=C_{2}(n)$

$0.25n=2.70+0.15n$

$0.10n=2.70$

$n=27$

∴ On purchasing 27 photos, cost for both the options is the same.

-2w(w+8) what is the answer

Julli [10]

-2w (w + 8)
Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
-2w (w + 8) = 0
The roots are then:
w1 = 0
w2 = -8
Assuming you only have to rewrite the expression, the answer is:
-2w ^ 2 -16w
Answer:
w1 = 0
w2 = -8
-2w ^ 2 -16w
