Two groups of friends go to a baseball game. one group bought 3 drinks and 2 pretzels for $16. the other group bought 5 drinks and 5 pretzels for $31.25. what is the price of one drink and one pretzel?

the price for one pretzel was $1.75

Step-by-step explanation:

d for drinks

p for pretzel

3d + 3p = 9

3d = 9 -3p

d = 3 - p

replace d = 3 - 9 into 4d + 2p = 8.5

4d + 2p = 8.5

4(3 - p) + 2p = 8.5

12 - 4p + 2p = 8.5

-2p = 8.5 - 12

-2p = -3.5

p = 1.75
