Answer :

Let's use the information to set up a system of equations:

Let x be the number of small drinks sold and y be the number of large drinks sold.

From the given information, we have:

x + y = 55  (equation 1)

4.25x + 5.75y = 298.25  (equation 2)

Now, we can solve this system of equations.

From equation 1:

x = 55 - y

Substitute x = 55 - y into equation 2:

4.25(55 - y) + 5.75y = 298.25

233.75 - 4.25y + 5.75y = 298.25

1.5y = 64.5

y = 43

Now, substitute y = 43 back into x = 55 - y:

x = 55 - 43

x = 12

12 small drinks and 43 large drinks were sold.
