Sal spent $24.18 on fruit. He bought a watermelon that cost $6.18, and he bought 6 oranges. How much did each orange cost? Sal used addition and then division to find the cost of each orange. Is this correct?
No, Sal used subtraction and then division to find the cost of each orange.
No, Sal did not calculate the cost of each orange correctly. To find the cost of each orange, he needs to subtract the cost of the watermelon from the total amount spent and then divide by the number of oranges. Let's go step-by-step to find the solution.
1. Subtract the cost of the watermelon from the total spent:
Total spent - Cost of watermelon = $24.18 - $6.18 = $18.00
2. Divide the remaining amount by the number of oranges to find the cost of each orange:
Cost of each orange = Remaining amount / Number of oranges = $18.00 / 6 = $3.00
Therefore, each orange cost $3.00, not using addition and then division.
Yes, Sal's approach of using addition and then division is correct to find the cost of each orange. Let's break it down step by step:
1. Sal spent a total of $24.18 on fruit.
2. He bought a watermelon that cost $6.18.
3. To find the cost of the oranges, we need to subtract the cost of the watermelon from the total amount Sal spent:
$24.18 - $6.18 = $18.00
4. Next, we divide the remaining cost ($18.00) by the number of oranges Sal bought (6) to find the cost of each orange:
$18.00 รท 6 = $3.00
Therefore, each orange cost $3.00. Sal's method of using addition and then division is correct in this case.
