Try to me fast drag each scenario to show whether the final result will be greater than the original value, less than the original value, or the same as the original value.

I'm at a bookstore with $\$35$ in my pocket and a $20\%$-off coupon. what is the cost of the most expensive book i can buy with my money and the coupon? (assume that there are books of every possible price in the bookstore. it's a large bookstore! )
