Question

Joanne is looking for a job as a teacher. She plans to send resumes to 123 schools in her county. Her local printer charges $23 per 100 copies, and sells them only in sets of 100. a. How many copies must Joanne purchase if she is to have enough resumes? b. How much will the copies cost her, including 8% sales tax?

Answer 1

She would have to buy two sets of 100 copies. (200 copies)
23 * 2 = $46
Sales tax : 46 * 0.08 = $3.68

ALL together : 46 + 2.68 = $48.68

Answer 2

She must buy 200 copies, 2 sets of 100.

Total payment=$49,68
