Answer:

Step-by-step explanation:

Let p represent the number of pens Nick sold. Then the revenue is ...

0.10p +0.05(1000 -p) = 74.50

0.05p = 24.50 . . . . . . eliminate parentheses, subtract 50

p = 490 . . . . . . . . . . . . multiply by 20

The number of pencils sold is then ...

pencils = 1000 -490 = 510

Nick's Printing Press sold 490 pens and 510 pencils.
