The answer is a............
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
Please include the instructions when you post a question. Thanks.
Use the formula A = P*e^(rt).
Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).
As an example: After 2 years you'll have A = $700*e^(0.065*2), or A=$797.18, in your account.
