Susan is buying cupcakes for her class. Each cupcake costs $2.99. There are 30 people in her class. What is the total cost of the cupcakes?
30 * $2.99 = $____
or,
30*$3 = $90
but subtract 1 cent for each of the cupcakes, since they only cost $2.99 each.
total cost is thus $89.70
To find the total cost of the cupcakes, you need to multiply the cost of each cupcake by the number of cupcakes that Susan needs to buy.
Step 1: Multiply the cost of each cupcake by the number of cupcakes:
$2.99 x 30 = $89.70
The total cost of the cupcakes is $89.70.
To find the total cost of the cupcakes, we need to multiply the cost of each cupcake by the number of cupcakes.
1. Calculate the total number of cupcakes by multiplying the number of people in Susan's class (30) by the number of cupcakes each person will get (assume each person gets one cupcake).
- Total number of cupcakes = 30 * 1 = 30
2. Multiply the cost of each cupcake ($2.99) by the total number of cupcakes to get the total cost.
- Total cost = $2.99 * 30 = $89.70
Therefore, the total cost of the cupcakes for Susan's class is $89.70.
