Let's represent the number of cakes sold as "x".
The sales from selling x cakes can be represented as 16x.
The expenditures include the cost of the booth and the ingredients. The cost of the booth is $52 and the cost of the ingredients for each cake is $3. Therefore, the total expenditure can be represented as 52 + 3x.
According to the problem, the sales will cover the expenditures. So, we can set up the equation:
16x = 52 + 3x
To solve for x, we can use the substitution method.
First, subtract 3x from both sides of the equation:
16x - 3x = 52 + 3x - 3x
Simplifying, we get:
13x = 52
Next, divide both sides of the equation by 13 to solve for x:
x = 52 / 13
Simplifying, we get:
x = 4
Therefore, the cooking club will have sold 4 cakes.
To find the sales and expenditures, we can substitute the value of x into the equations:
Sales = 16x = 16 * 4 = $64
Expenditures = 52 + 3x = 52 + 3 * 4 = $64
Therefore, the sales and expenditures will both be $64. The cooking club will have sold 4 cakes.
