Answer:
x =
will be the expression.
Step-by-step explanation:
In this question an expression has been given which represents the relation between average cost C and number of T shirts (x) manufactured.
We have to solve this expression for the value of x (number of T-shirts) in terms of C.
C = 5x + 410x
C = 415x
x = 
Therefore, x =
will be expression showing the number of T-shirts in terms of average cost.
I graphed this line below.
Start with an open dot on 7.
The reason we use an open dot is because x
does not equal 7, it is only greater than 7.
So from your open dot, draw an arrow to the right
to represent all numbers greater than 7.
Finally, state your answer in set notation if possible.
It is read as {x: x > 7}.
Here are the answers to the questions above. Given the problem, let us solve first for the cost of each store. At a local store, it costs $49.95. Since she has a 10% off discount, the amount that she will be paying is $44.955. Since, there is a 6.5% tax, the total amount she will be paying is $48.20. Now, for the online store, it costs $44.95 plus a shipping charge of $4.00 so the total would be $48.95. Given these results, it would be cheaper if she buys in the local store. Hope this helps.
