Problema Solution
At a local bakery, big cookies sell for 5.99 and pies sell for 9.99. The total number of pies and cookies sold on Monday was 25. If the sales total for Monday was 189.75, find the number of pies sold
Answer provided by our tutors
c + p = 25 - (1)
5.99 c + 9.99 p = 189.75 - (2)
multiply (1) by 5.99 and subtracting from (2) we have
4 p = 40 => p = 10
