Maria needs to save $187.50 per month in order to attend college.
First, subtract the $1,100 scholarship from the cost of college, or $10,100, to get $9,000. This is the amount that she needs to save after 4 years. Next, since she is saving monthly, we need to know how many monthly periods are in 4 years, so multiply 12 months/year by 4 years to get 48 monthly periods. Finally, divide the total amount needed ($9,000) by the monthly periods (48) to get $187.50. This answer would change if she earned any interest on her savings, and depending on the compounding period, if any, for such interest.

Answer:
The cost of each drink is $1.5
Step-by-step explanation:
Let us represent
The cost of snacks = x
The cost of drinks = y
50 snacks and 180 drinks will sell for $320
Hence:
50x + 180y = 320....... Equation 1
75 snacks and 100 drinks will sell for $225.
Hence:
75x + 100y = 225....... Equation 2
Combining both Equations together
50x + 180y = 320....... Equation 1
75x + 100y = 225....... Equation 2
Multiply Equation 1 by 75 and Equation 2 by 50 to eliminate x
3750x + 13500y = 24000..... Equation 3
3750x + 5000y = 11250....... Equation 4
Subtract Equation 4 from Equation 3
8500y = 12750
y = 12750/8500
y = $1.5
Therefore, the cost of each drink is $1.5
