Explanation:
Let's use "x" to represent the number of chocolate cakes sold and "y" to represent the number of vanilla cakes sold.
From the problem statement, we know that the bakery sold a total of 50 cakes, so we can set up an equation:
x + y = 50
We also know that the total sales were $200. If the chocolate cakes sold for $5 each and the vanilla cakes sold for $3 each, we can set up another equation for the total sales:
5x + 3y = 200
We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for y in terms of x:
y = 50 - x
Substituting this expression for y into the second equation, we get:
5x + 3(50 - x) = 200
Simplifying this equation, we get:
2x + 150 = 200
2x = 50
x = 25
So the bakery sold 25 chocolate cakes. To find the number of vanilla cakes sold, we can substitute x = 25 into the equation y = 50 - x:
y = 50 - 25
y = 25
So the bakery also sold 25 vanilla cakes.
Therefore, the bakery sold 25 chocolate cakes and 25 vanilla cakes.
