Jasmine wishes to purchase some trading cards. She has $\$7.50$ and the cards each cost $\$0.85$, tax included. What is the most number of cards she can buy?
To find the most number of cards she can buy, I want to divide her total amount of money by the cost per card. This will give me a decimal value, but I need to round it down to the nearest integer, since she cannot buy a fraction of a card. I can use long division or a calculator to perform the division. Using a calculator, I get $\frac{7.50}{0.85} \approx 8.82$. Rounding down, I get $8$ as the final answer.
