David is running a concession stand at a soccer game. He sells nachos and sodas. Nachos cost $1.50 each and sodas cost $0.50 each. At the end of the game, David made a total of $78.50 and sold a total of 87 nachos and sodas combined. Which system of equations represents this situation?

1.5x + 0.5y = 78.5 x + y = 87

1.5x + 0.5y = 78.5 1.5x + 0.5y = 87

x + y = 78.5 x + y = 87

x + y = 78.5 1.5x + 0.5y = 87

1.5x + 0.5y = 78.5 x + y = 87

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

The total earnings of David (78.50) must be equal to the product of the number of nachos sold (x) and the cost per nacho (1.50); plus the product of the number of sodas sold (y) and the cost per soda (0.50).

Mathematically speaking:

1.5 x +0.5y =78.5

And the sum of the number of nachos sold (x) and the number of sodas sold (y) must be equal to 87.

x+y= 87

So, the system is:

1.5x + 0.5y = 78.5

x + y = 87

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

d.) 48 units
