Final answer:
To determine the cost of two milkshakes when three milkshakes cost $9.75, first calculate the unit price by dividing $9.75 by 3 to get $3.25 per milkshake. Then multiply $3.25 by 2 to find that two milkshakes cost $6.50.
Step-by-step explanation:
The student has asked about the cost of milkshakes given a certain rate. If three milkshakes cost $9.75, we can find the unit price of one milkshake by dividing $9.75 by 3. Then, to find the cost of two milkshakes, we multiply this unit price by 2.
Steps to Calculate the Cost of Two Milkshakes:
- Find the cost of one milkshake by dividing the total cost of three milkshakes by the number of milkshakes: $9.75 ÷ 3.
- The result is the price per milkshake.
- Multiply the price per milkshake by 2 to find the cost for two milkshakes.
Unit Price Calculation: $9.75 ÷ 3 = $3.25 per milkshake.
Total Cost for Two Milkshakes: $3.25 × 2 = $6.50.
Therefore, two milkshakes cost $6.50 at the given rate.
