Answer:
The original price is $119
Step-by-step explanation:
<u>x + 4 > 4 + pi</u>
You could subtract 4 from each side.
Then you would have
<em> x > pi </em> .
That looks like a solution to me.
Let's use x as the number of questions she answered correctly. If we make an equation of out the question, it would be 8.7x+13=108.7 To solve the equation subtract 13 from both sides. So it will leave you with 8.7x=108.7-13, which is 8.7x=95.7. Divide both sides by 8.7, which will give you x=11. She answered 11 questions correctly.
