Notice that
so on the left side, a factor of <em>x</em> - 7 in the numerator and denominator can cancel
But we can only cancel them out as long as <em>x</em> ≠ 7 (because otherwise we'd have the indeterminate form 0/0 on the left side).
So, the equation is true for all <em>x</em> <u>except</u> <em>x</em> = 7. In set notation,
In interval notation,
Answer: $13.94
Step-by-step explanation:
Given : Bargain Feed Store has a markup rate of 14.1%.
The wholesale cost of bag of horse feed = $12.22
Price mark up = Mark up % x Whole sale cost
Price mark up =14.1% x $12.22
Price mark up
Then , the final price of bag of horse feed will be :-
Final price = wholesale cost +Price mark up
=$12.22+$1.72 = $13.94
Hence, the shop will charge $13.94 for a bag of horse feed that cost $12.22 wholesale.
