My question is: Ice cream costs $2.00 and toppings cost $0.50 per topping. How much does a sundae with 10 toppings cost? Your thoughts:
First find the total cost of the toppings: 10 toppings * $0.50 / topping = $5.00. Then add that amount to the cost of the ice cream: $5.00 + $2.00 = $7.00. The final answer: 7.
