The equation shows that the pastries that must be sold at $3.55 each in order to make a profit is 23.
<h3>How to calculate the expression?</h3>
Let the number of units be represented by x.
Based on the information given, the equation will be:
75 + (0.15 × x) = 3.55 × x
75 + 0.15x = 3.55x
3.55x - 0.15x = 75
3.40x = 75
x = 75/3.40
x = 23
Therefore, the number is 23.
