Given the following parameters

Cost of a notebook computer = $175

Cost of a desktop computer = $300

The cost of 15 notebooks and 16 desktop computers = 15(175) + 16(300)

The cost 15 notebooks and 16 desktop computers = 2,625 + 4800

The cost 15 notebooks and 16 desktop computers $7425

Hence the total cost of 15 notebooks, and 16 desktop computers is $7425

The cost of n notebooks = 175n

The cost of d desktop = 300d

Hence the total cost of n notebooks, and d desktop computers is 175n + 300d
