You are running a concession stand at a baseball game. You are selling pizza slices and sodas. Each pizza slice sells for $3.50 and each soda sells for $1.50. At the end of the night, you made a total of $800. You sold a total of 344 pizza slices and sodas combined. You must report the number of pizza slices sold and the number of sodas sold. What equations did you use to solve this, where P = the number of pizza slices sold and S = the number of sodas sold? (1 point) Responses 3.50S + 1.50P = 344 and P + S = 800 3.50S + 1.50P = 344 and P + S = 800 3.50P + S = 800 and P + 1.50S = 344 3.50P + S = 800 and P + 1.50S = 344 3.50S + 1.50P = 800 and P + S = 344 3.50S + 1.50P = 800 and P + S = 344 3.50P + 1.50S = 800 and P + S = 344
To solve this problem, we can set up the following equations:
Let P = the number of pizza slices sold
Let S = the number of sodas sold
The price of a pizza slice is $3.50 and the price of a soda is $1.50.
The first equation represents the total revenue from selling pizza slices and sodas combined, which should equal $800:
3.50P + 1.50S = 800
The second equation represents the total number of pizza slices and sodas sold, which should equal 344:
P + S = 344
So, the correct equations are:
3.50P + 1.50S = 800 and
P + S = 344
Let P = the number of pizza slices sold
Let S = the number of sodas sold
The price of a pizza slice is $3.50 and the price of a soda is $1.50.
The first equation represents the total revenue from selling pizza slices and sodas combined, which should equal $800:
3.50P + 1.50S = 800
The second equation represents the total number of pizza slices and sodas sold, which should equal 344:
P + S = 344
So, the correct equations are:
3.50P + 1.50S = 800 and
P + S = 344
