Answer: 225 hamburgers were sold on Monday.
Step-by-step explanation:
525 = h + c

-75
2h = 450
/2
h = 225
A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
You could replace x for 4
