Using the trial and error method, the number of pies sold was calculated as: 13 fries.
To solve a problem by using a trial and error method, we assume a possible value and check if it makes an equation true.
Let x represent the unknown number of pies that were sold, and y represent the price which is between 3 and 4 dollars.
x = ?
y = 3.35 (this is between 3.99 and 3.01)
We have 43.55/y = x. Therefore,
43.55/3.35 = 13
