We can find the slope by using rise/run
As expected, the slope is indeed undefined. The denominator can't be 0 but this one has denominator that's 0 which is undefined.
Meaning that, when the x-value for both ordered pairs are the same, the slope will be undefined.
For the graph, It should be like this below in the picture.
Answer:
The markup (in percentage) is 66.67%
<em>The markup (in dollars) is $33.92</em>
Step-by-step explanation:
First, we will find the sales price of the product (excluding sales tax).
Let sales price be "x", so we can say:
x increased by 6.25% is 90.10
<u>Note: </u> 6.25/100 = 0.0625
Thus, we can write an equation and solve for x now:
The markup is a percentage of the cost.
The markup is the difference in cost and sales price, divided by cost. Then we multiply by 100 to get percentage. So:
MarkUp =
The markup (in percentage) is 66.67%
In dollars, it will be $33.92
