Marcel and Floyd are playing games at an arcade. Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games. Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining. Jorge’s work is shown below.Let x = the number of games played.Jorge knows his answer is incorrect because it does not make sense to have a negative number of games. What is Jorge’s error?A. The variable x should represent the amount of money left.B. From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.C. The equation should have sums on both sides.D. From Step 2 to Step 3, Jorge should have subtracted 0.50x from both sides.

Can you help me with this question please? I will reward 20 points for best answer. * You don't have to solve the problem for me, I just want to know the formula and how to solve it. "When the fundraiser began, 600 people wanted to purchase the dance troupe’s T-shirts at $12 per T-shirt, but as the group increased the price of their T-shirts, they noticed a fall in the demand. For every $1 increase in price, the demand fell by 50 shirts. The dance troupe’s initial supply was short by 210 T-shirts which corresponded to an initial price of $9.75. For every $1 increase in price, they ordered 40 more T-shirts. Write a system of linear equations to represent both the demand and supply for the T-shirts. Let q represent the quantity of T-shirts and p represent the price."

A student's course grade is based on one midterm that counts as 10% of his final grade, one class project that counts as 25% of his final grade, a set of homework assignments that counts as 50% of his final grade, and a final exam that counts as 15% of his final grade. His midterm score is 74, his project score is 93, his homework score is 83, and his final exam score is 77. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.
