X^2 - 10 = 3x
X^2 - 3x - 10 = 0
(x - 5) (x + 2) = 0
x = 5 and x = -2
Answer: x = -2
First we must find the "10%" of the problem. Which is 250 dollars, because .10 times 2,500.
Next we must add the ten percent to 2,500. Which will be 2,750.
Then, we must find how much Linda earned for working for 25 hours. Use f(x)=5.25x to find the total amount. f(25)=5.25(25) is f(25)=131.25.
Last, we must add the total amounts, 131.25+2,750.
Your final answer is, 2,881.25
