A real estate salesperson bought promotional calendars and date books to give to her customers at the end of the year. The calendars cost $0.750.75 each, and the date books cost $0.500.50 each. She ordered a total of 500500 promotional items and spent $350350. How many of each item did she order?

Calenders= 400

Date book= 100

Explanation:

In this instance we will derive an equation to solve the problem.

Assume that quantity of calenders is q.

Therefore

500-q = number of date books

Total price = summation of (price *quantity)

$350= 0.75q+ 0.5(500-q)

350= 0.75q+ 250- 0.5q

350= 0.25q+ 250

0.25q= 350-250= 100

q= 100/0.25= 400

So calenders is equal to 400

And date books= 500-q= 500-400

Date books = 100
