Model rocket engines (or motors) are generally purchases in boxes of 24 or packages of 3.

If I want 32 engines I would need to purchase 1 box of 24 and 3 packages of 3 (I would end up with 1 extra engine). Write a program that calculates how many boxes and packages you must purchase to get a specific number of engines. Also enter the price of a box and a package and calculate the total cost of the purchase. Use integer division (/, %) to calculate the number of boxes and packages. Note: when printing out the answer the correct word (box/boxes, package/packages) should appear after the number. If the number is 0, don't print anything at all.

Example Output:

Enter the number of engines needed: 30

Enter the cost of a box of 24 engines: 65.95

Enter the cost of a package of 3 engines: 8.49

You will need to purchase 1 box and 2 packages of engines

at a total cost of $82.93.

-----

Enter the number of engines needed: 10

Enter the cost of a box of 25 engines: 65.95

Enter the cost of a package of 3 engines: 8.49

You will need to purchase 4 packages of engines

at a total cost of $33.96.
