Answer:
Step-by-step explanation:
Using FOIL, we can expand the polynomial on the left-hand side of the equation:
Next, let's move all of the terms to the left-hand side of the equation and combine like terms:
Now we can factor the quadratic:
This produces two equations to give us the two solutions:
The first solution:
and the second solution:
So the solutions to this problem are
3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
