Respuesta :

Answer:

$8,050 total

Step-by-step explanation:

notebooks: 13×400=5200

desktop: 19×150=2850

The cost to buy 13 notebooks and 19 desktop computers is $8050

Cost of notebook computers = $400

Cost of desktop computers = $150 each

The cost to buy 13 notebooks and 19 desktop computers will be:

= 400(13) + 150(19)

= 5200 + 2850

= $8050

The cost to buy n notebooks and d desktop computers will be:

= 400(n) + 150(d)

= 400n + 150d
