a. Write the function
b. To make ​$262.50 in​ sales, you would need to sell at least muffins.

a. The function that relates the sales and the number of muffins can be represented as:

s(m) = 2.25m

b. To make at least $262.50 in sales, you would need to sell at least 116 muffins.

s(116) = 2.25(116) = 261.00 < $262.50

s(117) = 2.25(117) = 263.25 > $262.50

Therefore, you would need to sell at least 117 muffins to make at least $262.50 in sales.
