Your school is having a bake sale, and you are running the booth for the Dance Club. You are selling brownies for $0.50 and cookies for $0.35. You look down at your logs and see you sold a total of 50 items. You notice that you sold 4 more cookies than rice crispy treats and 3 more brownies than cookies. If you made a total of $24.40 from the booth, how much did you sell each rice crispy for in dollars?

Given the equations \( 3x+6y^2 = 66 \) and \(y^2=x+5 \), what is y?

In a video game, y armor costs 3 times as many coins as a x armor. You traded in your set of x armor and got back the full cost you had paid for it. You then bought a set of y armor. After buying the set of y armor, you had 3,500 fewer coins in your account than you did after you received coins for selling back the x armor. How much does the y armor cost in coins?

If the system of equations \(3x-2y = 8\) and \(\frac{3x}{2}+5y=10\) has a solution of the form (x,y), what is the value of x?

You are playing Skee-Ball at an arcade. You have a total of 9 balls to roll into holes worth 10, 25, 50, and 100 points. You were able to score the 100-point hole twice and the 50-point hole a third as many times as the 25-point hole. Your final score was 355 points. Assuming you earned points on each roll, how many times did you score 10 points?

You have $8.00 in change in a jar and are going to the coin exchange to get that amount in dollar bills. You have $4.00 in quarters, half that dollar value in dimes, and 1.5 times as many nickels as dimes. The rest of your coins are pennies. What is the total number of coins you are bringing to the exchange? (The values of a quarter, dime, nickel, and penny are $0.25, $0.10, $0.05, and $0.01 respectively.)

In a video game, there are two stores from which you can buy items. The first store takes yellow coins, and the second store takes blue coins. The owner of the second store has you solve the following problem in order to unlock his store: If 1 blue coin is worth 5 times as much as 2 fewer than 4 yellow coins, 20 blue coins are worth as much as how many yellow coins?
