A teacher bought 7 packs of dominoes for a math game. Each pack had 55 dominoes. The teacher already had 118 dominoes to use in the game. Estimate how many dominoes the teacher had for the game.

the teacher had 503 dominoes for the game.

Step-by-step explanation:

In order to find the answer, first you have to find the amount of dominoes the teacher purchased by multiplying the number of packs for the number of dominoes in each pack:

385+118=503

According to this, the answer is that the teacher had 503 dominoes for the game.
