A school needs to buy new notebook and desktop computers for its computer lab. The notebook computers cost $150 each, and the desktop computers cost $200 each. How much would it cost to buy 20 notebooks and 11 desktop computers? How much would it cost to buy nn notebooks and dd desktop computers?
Total cost, 20 notebooks and 11 desktop computers:
Total cost, nn notebooks and dd desktop computers:
Total cost, 20 notebooks and 11 desktop computers:
The cost of 20 notebooks would be 20 x $150 = $<<20*150=3000>>3000.
The cost of 11 desktop computers would be 11 x $200 = $<<11*200=2200>>2200.
Therefore, the total cost would be $3000 + $2200 = $<<3000+2200=5200>>5200.
Total cost, nn notebooks and dd desktop computers:
The cost of nn notebooks would be nn x $150 = $150nn.
The cost of dd desktop computers would be dd x $200 = $200dd.
Therefore, the total cost would be $150nn + $200dd.
