Answer:
Step-by-step explanation:
You have the following quadratic equation given in the problem:
You must make the equation equal to zero, as following:
Add like terms:
Now, to factor the equation, you must find two numbers whose sum is -2 and whose product is -15. Therefore, you have:
The number is 24. If 8 is one third of the number, you multiply 8 by 3 to find the number, which is 24.
Magazines that cost $3.95 each, <span>m represent the number of magazines
</span>books that cost $8.95 each, <span>b represent the number of books
</span><span>total of $47.65
</span><span>
so
equation
3.95m + 8.95b = 47.65</span>
