Answer:
2 3/8 (2.375)
Step-by-step explanation:
You can substitute m with 1/4, giving you the equation 2(1/4^2) + 9(1/4). You can then solve for the answer.
How to solve:
2(1/4^2) + 9(1/4)
2(1/16) + 9/4
1/8 + 9/4
1/8 + 18/8
19/8
2 3/8 (2.375)
To solve this problem, you will need to set up a proportion.
Let x = the unknown cost of the books.
Assuming the cost of books stays constant, you can crossmultiply and solve for x.
x = 1.95(6)
x = 11.70
Six books will cost $11.70 if 1 book cost $1.95.
