Answer the following: 1. As the number of kilos(x) increases, what happens to the total cost(y)? Will it increase,
decrease or remain the same?
2. Using this pattern, how much is the total cost(y) if the number of kilos(x) bought is 5?
3. What mathematical operation did you apply? Is there a constant number involved?
Explain the process that you have discovered.
From the activity, it can be observed that:
1. As the number of kilos(x) increases, the total cost(y) also increases.
2. In finding the cost of rice(y), the number of kilos(x) is multiplied by a constant number which
is equal to 40.
3. The mathematical statement that describes the relation is y=40x, where y represents the cost
of rice and x represents the number of kilos.
