billy has $3.00. bubble gum costs $.30. he bought four pieces how much money does Billy have left

Answer 1

To find out how much money Billy has left after buying four pieces of bubble gum, we can start by calculating the total cost of the gum.

The cost of one piece of bubble gum is $0.30. If Billy buys four pieces, the total cost will be:

\[ \text{Total cost} = 4 , \text{pieces} \times 0.30 , \text{dollars/piece} = 1.20 , \text{dollars} \]

Now, to find out how much money Billy has left, we subtract the total cost from the amount he initially had:

\[ \text{Money left} = 3.00 , \text{dollars} - 1.20 , \text{dollars} = 1.80 , \text{dollars} \]

Therefore, Billy has $1.80 left.
