Oranges are sold at 5 for bol. How much does a boy pay for 10 oranges?
Answer (1)
Determine the cost of 5 oranges: 1 bol.
Calculate the cost per orange: 5 1 = 0.2 bol.
Multiply the cost per orange by 10 to find the total cost: 10 × 0.2 = 2 bol.
The boy pays 2 bol for 10 oranges.
Explanation
Understanding the Problem Let's break down this problem step-by-step to make sure we understand how to find the cost of the oranges.
Finding the Cost per Orange We know that 5 oranges cost 1 bol. We want to find out how much 10 oranges cost. First, we can find the cost of a single orange. Since 5 oranges cost 1 bol, we can write this as a ratio: 5 oranges / 1 bol.
Calculating Cost per Orange To find the cost of 1 orange, we divide the total cost by the number of oranges: 5 oranges 1 bol = 0.2 bol per orange . So, each orange costs 0.2 bol.
Calculating Total Cost Now that we know the cost of one orange, we can find the cost of 10 oranges. We multiply the cost per orange by the number of oranges we want to buy: 10 oranges × 0.2 orange bol = 2 bol .
Final Answer Therefore, the boy pays 2 bol for 10 oranges.
Examples
Imagine you are at a farmer's market. You see apples being sold at 3 apples for $2. You want to buy 9 apples. Using the same method, you would first find the cost per apple ($2/3 = $0.67 per apple) and then multiply by the number of apples you want (9 apples * $0.67/apple = $6.03). This helps you quickly calculate the total cost before making your purchase.
