Answer: Option A, 
Answer:
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:
7*55=385
Now, since the stament indicates that the teacher already had 118 dominoes to use in the game, you have to add this amount to the number of dominoes that were purchased:
385+118=503
According to this, the answer is that the teacher had 503 dominoes for the game.

To solve this problem, I would set up an equation, letting x represent our unknown value. First, we must convert 12% to its decimal equivalent, by dividing 12/100. We do this because percentages represent parts of a total 100%, so we must take the percentage (part) and divide it by 100 (whole). Since 12/100 = 0.12, we can create our equation:
182 is 12% of a number
*Remember that "is" means equals in math and "of" means multiplication*
182 = 0.12 * x
OR
182 = 0.12x
To solve this equation, we must divide both sides of the equation by 0.12 to get the variable x alone on the right side of the equation.
x = 1516.66666667
Therefore, your answer is option B, 1516.7.
Hope this helps!
