Let x be the number of small chocolates purchased and y be the number of large chocolates purchased. From the information given in the question, we can set up a system of equations as follows:
x + y = 10 (total number of chocolates purchased) 0.5x + 1.5y = 9.5 (total cost of the chocolates)
We can solve for x and y by using either substitution or elimination method. Let's use the substitution method:
x = 10 - y (substitute x by 10 - y in the second equation)
0.5(10 - y) + 1.5y = 9.5
5 - 0.5y + 1.5y = 9.5
Simplifying the equation:
y = 4
Substituting y = 4 in the first equation:
x + 4 = 10
x = 6
Therefore, the customer purchased 6 small chocolates and 4 large chocolates. The answer is A) 6 small, 4 large.
