Answer:
At most, Jermain can purchase 2 lbs. of pears.
Step-by-step explanation:
Using the Fundamental Counting Theorem, it is found that 128 different combinations are possible.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem:
- There are two options for the sleeve length, hence .
- There are four options for the size, hence .
- There are four options for the color, hence .
- There are four options for the artwork, hence .
Thus, the number of combinations is given by:
N = 2 x 4 x 4 x 4 = 128.

Step-by-step explanation:
x = -4y + 6
Now,
Substituting the value of x on 2x + 9y = 16, we get -.
2(-4y + 6) + 9y = 16
-8y + 12 + 9y = 16
y = 16 - 12
<h3>y = 4</h3>
Now,
Substituting the value of y on 2x + 9y = 16, we get -
2x + 9(4) = 16
2x = 16 - 36
2x = -20
<h3>x = -10</h3>
Hence,
The value of x is -10 and y is 4.
