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.

Answer: 1/4 or 25%
Step-by-step explanation: The probability of drawing any card is equal because there is only 1 of each number. 4 is pulled out and not replaced, so there are 4 numbers instead of 5; the denominator is 4. The probability of 6 is 1/4, because there is one 6 out of four numbers. The suggested answer is 1/4, but some tests or questions will ask for the percent specifically.
