Suppose you want to buy some goldfish for your new aquarium. At the local pet store, one goldfish costs $2.99. Which expression could you use to compute the cost of 6 goldfish?

Answer 1

To compute the cost of 6 goldfish, you can use the expression \( 6 \times 2.99 \). This expression represents the multiplication of the number of goldfish (6) by the cost of each goldfish ($2.99).

So, the expression is: \[ 6 \times 2.99 \]
