Yes, it makes sense to represent the relationship between the amount saved and the number of months with one constant rate. The relationship is 35x+ 100.
<h3>
Relationship between the amount saved and the number of months</h3>
After 1 month, Jane will saved=$35+$100
After 1 month, Jane has saved=$135
Hence,
Let x represent the number of months
Since every month she saved $35 which inturn means that in x number of months she can save 35x. Based on this the relationship between the amount saved and the number of months is 35x +100.
Therefore it makes sense to represent the relationship between the amount saved and the number of months with one constant rate. The relationship is 35x+ 100.

The probability that the first two electric toothbrushes sold are defective is 0.016.
The probability of an event, say E occurring is:

Here,
n (E) = favorable outcomes
N = total number of outcomes
Let X = the number of defective electric toothbrushes sold.
The number of electric toothbrushes that were delivered to a store is n = 20.
The number of defective electric toothbrushes is x = 3.
The number of ways to select two toothbrushes to sell from the 20 toothbrushes is:


The number of ways to select two defective toothbrushes to sell from the 3 defective toothbrushes is:


Compute the probability that the first two electric toothbrushes sold are defective as follows:
P (Selling 2 defective toothbrushes) = Favorable outcomes ÷ Total no. of outcomes

Thus, the probability that the first two electric toothbrushes sold are defective is 0.016.
