A. assuming the sales tax is already added to the 72.60 all you have to do is add 20%
The answer to this rests on knowing that there are four properties of multiplication (which your teacher will likely expect you to know...):
These are:
1. commutative
2. associative
3. multiplicative identity
4. distributive
I won't define each of these -- they should be in your notes or textbook. Look them up.
In this case, we are multiplying three terms together -- on the left hand side the parentheses mean to multiply a and b first, then multiply that by 3. On the right hand side, we multiply b times 3 first, and then multiply the product by a.
This would be an example of the associative property of multiplication: when three or more factors are multiplied together, the product is the same regardless of how the factors are grouped.
Hope this helps!
Good luck
Answer:
A
Step-by-step explanation:
If the number of people in the theater must be under 240, then there must be less than 10 seats in each row on the floor to meet fire safety regulations.
if X=10 then, 15 times 10 plus 90 = 240.
Since the number of people must be under 240, there must be less than 10 seats in each row on the floor.
