Robert's Coffee and Creamer Budget
What are Robert's requirements for the ratio of creamer to coffee?
Robert will only drink coffee if he has exactly 5 packets of creamer for every cup of coffee.
How does Robert calculate the total cost of coffee and creamer?
To calculate the total cost, Robert considers the price of coffee at $3.00 per cup and creamer at $0.25 per packet.
Robert's Requirements for the Ratio of Creamer to Coffee:
Robert treats coffee and creamer as perfect complements, requiring exactly 5 packets of creamer for every cup of coffee.
Calculating the Total Cost of Coffee and Creamer:
To determine the total cost, we need to consider the prices of coffee and creamer. Each packet of creamer costs $0.25, so the cost of creamer can be calculated by multiplying the price per packet by the number of packets (x).
Robert's Requirements for the Ratio of Creamer to Coffee:
Robert has a very specific ratio he adheres to when preparing his coffee – for every cup of coffee, he must have exactly 5 packets of creamer on hand. This requirement shows just how particular Robert is about his coffee preferences and the importance he places on this specific ratio.
Calculating the Total Cost of Coffee and Creamer:
To calculate the total cost of coffee and creamer, we first need to determine the cost of creamer. With each packet of creamer priced at $0.25, we can calculate the total cost of creamer by multiplying the price per packet by the number of packets, denoted as x. This gives us the equation: Cost of creamer = $0.25 * x.
Next, to find the total cost of coffee and creamer, we need to add the cost of coffee to the previously calculated cost of creamer. Substituting the equations, we get: Total cost = $3.00 * (x/5) + $0.25 * x. This formula accounts for both the price of coffee and the required ratio of creamer to coffee.
By plugging in a specific value for x, such as 20 packets of creamer, we can calculate the total cost. Substituting x = 20 into the equation gives us: Total cost = $3.00 * (20/5) + $0.25 * 20. Simplifying this equation leads to: Total cost = $12.00 + $5.00 = $17.00.
Therefore, if Robert has 20 packets of creamer to maintain his strict creamer-to-coffee ratio, the total cost of coffee and creamer would amount to $17.00. This meticulous attention to detail highlights Robert's commitment to his coffee preferences and the importance he places on the perfect balance of creamer in his cup.
