Question 112379: I need help with this word problem also please, don't know how to start off the equation. Any help is appreciated.
For a holiday party, Marcus is making a seven-layer torte, which consists of seven 9-inch diameter cake layers with a cream topping on each layer. He knows that one recipe of cream will cover 65 square inches of cake. How many batches of the topping must he make to complete his torte?

You can put this solution on YOUR website!
First, you can write the equation for the amount of topping needed per layer of cake. The number of cake layers is 7 and each layer is 9 inches in diameter, which means the radius is half of that or 4.5 inches.
So the area of one layer is: or =sq. in.
Let the number of batches of topping be B and each topping will cover 65 sq. in. of cake.
So you can write:

Round up to the nearest integer.
