The cost of the apples is a function of their weight option (A) is correct because the independent variable (x) is the weight of the apples.
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
- A. The cost of the apples is a function of their weight.
- B. The weight of the apples is a function of the number of apples.
- C. The cost of the apples is a function of the type of apples.
- D. The weight of the apples is a function of their cost.
From the graph:
The y-axis is representing the cost(c) of the apples in dollars and
The x-axis is representing the weight(w) of the apples in pounds.
c = f(w)
The independent variable (w) is the weight of the apples
The dependent variable (c) is the cost of the apples
Thus, the cost of the apples is a function of their weight option (A) is correct because the independent variable (w) is the weight of the apples.

Answer:
1. $37.70 of interest
2. Jeans Junction
Step-by-step explanation:
1. For simple interest, we use the equation where
- P is the principle or starting value
- A is the total amount after interest and a period of time
- r is the rate at which interest gathers as a decimal
- t the time in years.
For this problem, we know P=$580, r=6.5%=0.065, t=1 year. We substitute into the formula and simplify to find the total amount A.
Using this total amount we can subtract the original principle to find the amount of interest.
617.7-580=$37.70 of interest
2. Jeans Plus sells jeans for $25 a pair At regular price, if I bought 3 I would spend 3j=s(25)=$75 and then received $10 off. SO I would spend $65 total.
Jeans Junction also sells jeans for $25 and will give me 15% off. This means I would pay 85% or 0.85 of the price (100-15=85). So if I buy 3, I would spend 3j=3(250=75. Then I can multiply 75(0.85)=63.75. This is the better deal because I spend less.
