Question

a set of 3 books costs $59.99. estimate the cost of each book. options: $10.00, $40.00, $30.00, $20.00

Explanation:

Step1: Round the total cost

Round $59.99$ to a number divisible by 3, so we take $60$ (since $59.99\approx60$).

Step2: Divide by the number of books

To find the cost per book, divide the rounded total by 3: $\frac{60}{3} = 20$. So the estimated cost per book is around $20.00$.

Answer:

\$20.00
