Make up a word problem whose solution require the expression: (2s+15)x3 20÷4 Solve it step-by-step.

Here is a word problem whose solution requires the given expression:

A baker makes 5 cookies on Monday. On Tuesday, she makes twice the number of cookies she made on Monday. On Wednesday, she makes the same number of cookies as she made on Monday. She then combines the cookies from Tuesday and Wednesday. She sells 3 times this combined amount. Later, she finds 20 cookies are burnt and divides them equally among 4 bins for disposal. How many cookies did she sell after accounting for the burnt ones?

Now, let's solve the expression $(2s + 1s) \times 3 - 20 \div 4$ using $s=5$ as per the word problem.
