Bananas are on sale for $0.40 a pound, and you have a coupon for $0.25 off your total purchase. Write a function rule for the cost of n pounds. How much would 30 pounds of bananas cost?
A) C(n)=0.25n-0.40;$7.10
B) C(n)=0.4n-0.4;$11.60
C) C(n)=0.4n-.025;$11.75
D) C(n)=0.4n;$12.00
My best answer is C is that correct
agree
100% correct thank U
I hope you're right, this is my answer too
does anyone know the test answers?

Well, in this case, your answer is not correct. But don't worry, I'm here to help you!
To find the function rule for the cost of n pounds of bananas, let's break it down:
The cost per pound is $0.40, so we multiply the number of pounds by $0.40. This gives us 0.4n.
Then, we subtract the coupon of $0.25 from the total purchase. So the function rule for the cost of n pounds would be:
C(n) = 0.4n - 0.25.
Now let's calculate the cost of 30 pounds of bananas using this function:
C(30) = 0.4 * 30 - 0.25 = 12 - 0.25 = $11.75.
So the correct answer is option C) C(n) = 0.4n - 0.25; $11.75.
Now you have your answer! Keep in mind, though, that my primary goal is to bring a smile to your face, so I hope you found this explanation entertaining!
To find the correct function rule for the cost of n pounds of bananas, we need to consider the given information.
First, let's break down the cost of the bananas without the coupon. The price is $0.40 per pound, so the cost of n pounds would be 0.40n.
Next, we need to factor in the coupon. The coupon gives a discount of $0.25 off the total purchase. So, we subtract $0.25 from the cost of n pounds of bananas.
Combining the two calculations, the function rule for the cost, C(n), would be:
C(n) = 0.40n - 0.25
Now, let's calculate the cost of 30 pounds of bananas using this function rule:
C(30) = 0.40(30) - 0.25
C(30) = 12 - 0.25
C(30) = $11.75
Therefore, the correct answer is C) C(n) = 0.4n - 0.25; $11.75.
Bananas are on sale for $0.50 a pound, and you have a coupon for $0.15 off your total purchase. Write a function rule for the cost, c, of n pounds.
c = 0.5n - 0.15
c = 0.5n
c = 0.5n + 0.15
c = 0.15n - 0.50
