Write a function rule for the total cost.

One frozen yogurt store sells frozen yogurt for $3.00 per cup and $1.25 per topping. Write a linear equation to show the total cost of a cup of frozen yogurt. Then calculate the total price for one cup of frozen yogurt with 4 toppings.
A. y= 1.25x +;$$5.00
B. y= 3x + 1.25;$13.25
C. y= 1.25x+3;$8.00
D. y= 5x+3;$8.00
Is the answer C?? Thank you

y=1.25x+3;$8.00

Oh, I'd love to give you the answer, but I just can't resist adding a hint of humor to it. So, hold on tight!

The total cost of a cup of frozen yogurt with toppings can be calculated using the linear equation y = 1.25x + 3. Here x represents the number of toppings, and 1.25 is the cost per topping. Now, let's do some math magic!

If you want to find the total price for one cup of frozen yogurt with 4 toppings, you simply plug in x=4 into the equation. Let's summon the math gods for the calculation!

1.25(4) + 3 = 5 + 3 = 8

Voila! The total price for one cup of frozen yogurt with 4 toppings is $8. So, my dear friend, the answer you're looking for is C. Keep enjoying the creamy goodness with a sprinkle of humor!

The correct answer is actually B. Let's break it down step by step:

The given information states that the frozen yogurt costs $3.00 per cup and $1.25 per topping. To calculate the total cost, we need to consider both the cup and the toppings.

We can represent the total cost as a function of the number of toppings (x). Since the cost of the cup is fixed at $3.00, the linear equation representing the total cost can be written as:

y = 3x + (1.25) * x

Simplifying this equation gives:

y = 3x + 1.25x

Combining like terms:

y = 4.25x

So, the correct equation to represent the total cost is: y = 4.25x.

Now, to calculate the total price for one cup of frozen yogurt with 4 toppings, we substitute x = 4 into the equation:

y = 4.25 * 4
y = 17

Therefore, the total price for one cup of frozen yogurt with 4 toppings is $17.00.

So, the correct answer is B.

To write a function rule for the total cost, we need to consider the cost per cup of frozen yogurt and the cost per topping.

The cost per cup of frozen yogurt is $3.00, and the cost per topping is $1.25. The total cost of a cup of frozen yogurt can be calculated by adding the cost of the frozen yogurt and the cost of the toppings.

So, the linear equation for the total cost, y, can be written as:

y = 3.00 + 1.25x

Where x represents the number of toppings.

To calculate the total price for one cup of frozen yogurt with 4 toppings, we substitute x = 4 into the equation:

y = 3.00 + 1.25(4)
= 3.00 + 5.00
= 8.00

So, the total price for one cup of frozen yogurt with 4 toppings is $8.00.

Therefore, the correct answer is C. y= 1.25x+3; $8.00.
