Answer:
146 pieces of candy per canister.
Step-by-step explanation:
876 ÷ 6 = 146
This is a classic example of where you would need to use the process of elimination. Let's start with answer A, 3 classes.
If A were to be correct, 3 classes of 45 minutes each would be 132 greater than the amount he paid, 3 classes worth $12. We could easily express this as a math equation:
45 * 3 = 132 + (12 * 3) Then, all you would have to do is simplify:
135 = 132 + 36
135 = 168
Obviously this equation isn't true, and you can continue with answer choice B.
But wait... there's a better way. Using this starting equation, we can come up with a formula to solve for c, the number of classes. Let's take our starting equation:
45 * 3 = 132 + (12 * 3) Now, let's turn all the 3s into cs.
45c = 132 + 12c Then, using algebra, we can solve this equation.
-12c - 12c
33c = 132
33c/33 = 132/33
c = 4
And finally, we have our answer, B! I hope both methods help you in your further studies.
Exponential relationships are relationships where one of the variables is an exponent. So instead of it being '2 multiplied by x', an exponential relationship might have '2 raised to the power x': Usually the first thing people do to get a grasp on what exponential relationships are like is draw a graph.
Doing so you'll get the answer
