Step-by-step explanation:
Answer:
X=12
Step-by-step explanation:
I did this in my head but if you need the explaination tell me in the comments.
You would use PEMDAS. So there are no P (parenthesis) so we move onto E (exponents). Since there are none of that we move onto M (multiplication) which is shown with (3 x 4). So that would be our first operation.
Let

represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:

. Now, we know that the the cost of materials is 30 dollars and the cost of labor is 0.1 dollars, so the total coast to produce

hard drives will be:

.
Now the only thing left is add t<span>he cost of equipment to complete our function:
</span>

We can conclude that the equation that could represent the cost function for making x hard drives is <span>
f(x)=30.1x+10,000</span>
