Mr. Thompson is buying rulers for his class.

Question

Which option gives Mr. Thompson the best price per ruler?

A. 4 rulers for $1.00
B. 50 rulers for $15.00
C. 100 rulers for $20.00
D. 200 rulers for $30.00

Answer 1

To find the price per ruler for each option, divide the total cost by the number of rulers.

For option A, 4 rulers for $1.00, the price per ruler is 1.00 / 4 = $0.25 per ruler.

For option B, 50 rulers for $15.00, the price per ruler is 15.00 / 50 = $0.30 per ruler.

For option C, 100 rulers for $20.00, the price per ruler is 20.00 / 100 = $0.20 per ruler.

For option D, 200 rulers for $30.00, the price per ruler is 30.00 / 200 = $0.15 per ruler.

Therefore, option D gives Mr. Thompson the best price per ruler.
