Question 1144110
.
<pre>
Let the cost of a small drink be  x  cents  (the unknown value under the question).


Then the cost of a large drink is (x+50) cents.


Then the condition says that the total cost of 3 small drinks and 2 large drinks is 350 cents


    3x + 2*(x+50) = 350  cents.


Simplify this equation and solve it for x :


    3x + 2x + 100 = 350

    5x            = 350 - 100

    5x            = 250

     x            = 250/5 = 50 cents.


<U>ANSWER</U>.  The small drink costs 50 cents, or $0.5.
