Two equations can be generated from the equation above, one for Package A and the other for Package B.
(Package A) 3x + 2y = 18
(Package B) 8x + 6y = 50
Solving simultaneously for the values of x and y gives, x = 4 and y = 3. Hence, each birthday card costs $4.
The answer is c.

The probability notation for the probability of choosing a green marble is P(G)
<h3>What is probability?</h3>
This is simply defined as the extent to which something is likely to occur.
The probability that an event will occur is given as the ratio of the number of favorable outcomes to the total number of outcomes.
<h3>How to determine the probability notation</h3>
Probability notation is a symbol used in indicating the probability of an occurring event. Since our focus is on the probability of obtaining a green marble, then the probability notation will be P(G). This is illustrated below:
- Event of green marble = nG
- Total event = nT
- Probability of green marble = P(G)
P(G) = nG / nT
