A real estate salesperson bought promotional calendars and date books to give to her customers at the end of the year.
The calendars cost ​$0.40 ​each, and the date books cost ​$0.50 each.
She ordered a total of 500 promotional items and spent ​$210.
How many of each item did she​ order?
------
Equations:
Quantity:: c + d = 500 items
Value:: .4c + .5d = 210 dollars
------------------
4c + 4d = 2000
4c + 5d = 2100
--------------------
Subtract and solve for "d":
d = 100 (# of date books)
----
c = 500 - 100 = 400 (# of calendars)
