Sally decides to buy quarts of ice cream at $5 each and boxes of pizza at $10 each for her softball team. Part 1) Write an algebraic expression that represents the total cost of the food if Sally buys x quarts of ice cream and y boxes of pizza.

Part 2) What is the total cost of Sally’s purchase if x=4 and y=5? Be sure to show your work.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
