All the boxes are about the same size, so you find the number of boxes in the shipment. There are 27 total boxes. The bill shows the school paid $10,950. In the catalog, the price of a new trumpet is $350 and the price of a new trombone is $475. 1. Write an equation representing the total number of instruments. 2. Write an equation representing the total cost. 3. Using your equations from Exercises 1 and 2, write and solve the linear system. 4. Choose a different method from the method you used in Exercise 3 to check your results. 5. How many trumpets did your school receive? How many trombones? \r
