Question

a small chocolate cake with walnuts,raspberries,and sprinkles costs $27.50. how much does each topping cost?

Answer 1

If a small cake equals $20 then you can remove that completely from the cost.

$27.50-$20=$7.50

Now, you are left with the three toppings; walnuts, raspberries, and sprinkles. Since you know you have three toppings you can divide the $7.50 by three

$7.50/3= $2.50

The answer to the problem is that each topping equals $2.50.
