Hope it helps!
Step-by-step explanation:
The graphs of quadratic functions are called parabolas. Here are some examples of parabolas. All parabolas are vaguely “U” shaped and they will have a highest or lowest point that is called the vertex. Parabolas may open up or down and may or may not have x -intercepts and they will always have a single y -intercept.
The graph of a quadratic function is a U-shaped curve called a parabola. The sign on the coefficient a of the quadratic function affects whether the graph opens up or down. If a<0 , the graph makes a frown (opens down) and if a>0 then the graph makes a smile (opens up).

Are you just adding the first two numbers and multiplying by 2, then doing the second parenthesis? If so, the answer is 87
If she already had savings of $125.75, and she earned $185 at her summer job, that means she has a total of $310.75 ($125.75 + $185 = $310.75).
If she then buys a $23.50 T-shirt, her total savings amounts to $287.25, because $310.75 - $23.50 = $287.25.
So the final answer is $287.25 :)
