On Monday the office staff at your school paid 8.77 for 4 cups of coffee and 7 bagels. On Wednesday they paid 15.80 for 8 cups of coffee and 14 bagels. Can you determine the cost of a bagel

Let the number of cups of coffee be c
Let the number of bagels be b.
Since cost = Price * Quantity, we're given two equations:

1. 7b + 4c = 8.77
2. 14b + 8c = 15.80

We have a system of equations. We can solve this 3 ways:

1. Substitution Method
2. Elimination Method
3. Cramer's Rule

No matter which method we use, we get the same answer

• The system is inconsistent. Therefore, we have no answer.
