Answer:
pretzels = 10
drinks = 6
Step-by-step explanation:
Let d = number of drinks
p = number of pretzels
4d+ 4.75p = 71.50
d+p = 16
Solving this for d
d = 16-p
Substituting this into the first equation
4(16-p)+ 4.75p = 71.50
Distribute
64 - 4p +4.75p = 71.50
Combine like terms
64 +.75p = 71.50
Subtract 64 from each side
64 -64 +.75p = 71.50-64
.75p = 7.5
Divide each side by .75
.75p/.75 = 7.5/.75
p =10
Now we can find the number of drinks
d = 16-p
16-10
