Answer:
<u>Option C</u> is equal to 7^1/3
N=-6
-6 minus 6 is -12
-12 /3 is -4 since the negative doesn’t cancel out
<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
.
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
.
Let us assume both costs are the same if we purchase
photos.
So, 



∴ On purchasing 27 photos, cost for both the options is the same.
Hypotenuse by Pythagoras theorem = 407.83.
