Transcript text: The table shows how much a fruit bar charges for their fruit cups. Write an expression to show how much it costs to buy a small cup of fruit with no toppings, and a large cup of fruit with $x$ toppings. Then, find the total cost for a small cup of fruit with no toppings, and a large cup of fruit with 3 toppings.
Write an expression for the total cost of a small cup of fruit with no toppings, and a large cup of fruit with $\times$ toppings.
Solution
Solution Steps
To solve this problem, we need to create expressions for the cost of a small cup of fruit with no toppings and a large cup of fruit with \( x \) toppings. The cost of a small cup is given directly, while the cost of a large cup with toppings involves adding the base cost of the large cup to the cost of the toppings. Finally, we calculate the total cost for a small cup with no toppings and a large cup with 3 toppings by substituting \( x = 3 \) into the expression for the large cup.
Step 1: Define the Costs
The cost of a small cup of fruit is given as \( C_{\text{small}} = 2.75 \). The cost of a large cup of fruit is \( C_{\text{large}} = 4.25 \), and the cost per topping for the large cup is \( C_{\text{topping}} = 0.30 \).
Step 2: Write the Expression for Total Cost
The total cost \( C_{\text{total}} \) for a small cup with no toppings and a large cup with \( x \) toppings can be expressed as:
\[
C_{\text{total}} = C_{\text{small}} + (C_{\text{large}} + x \cdot C_{\text{topping}})
\]
Step 3: Substitute for Specific Values
For the specific case of a large cup with 3 toppings (\( x = 3 \)):
\[
C_{\text{total}} = 2.75 + (4.25 + 3 \cdot 0.30)
\]
Step 4: Calculate the Total Cost
Calculating the cost of the large cup with 3 toppings:
\[
C_{\text{total}} = 2.75 + (4.25 + 0.90) = 2.75 + 5.15 = 7.90
\]
Final Answer
The total cost for a small cup of fruit with no toppings and a large cup with 3 toppings is
\[
\boxed{7.90}
\]
