Ivan bought 4.6 pounds of beef at the market for total of $36.57. He calculated that the price per pound of the beef was $0.79 per pound . Explain why Ivan's calculation cannot be correct.
ummh, because (4.6)(0.79) is not equal to 36.57 ??
Ivan's calculation cannot be correct because if the total price of 4.6 pounds of beef is $36.57, then the price per pound cannot be $0.79 per pound.
To verify this, we can multiply the weight of the beef (4.6 pounds) by the price per pound ($0.79):
4.6 pounds * $0.79/pound = $3.634
As we can see, multiplying the weight (4.6 pounds) by the price per pound ($0.79) gives us a value of $3.634, which is significantly less than the actual total price of $36.57. Therefore, Ivan's calculation of $0.79 per pound cannot be correct.
To determine why Ivan's calculation cannot be correct, we need to understand the problem. Ivan bought 4.6 pounds of beef for a total of $36.57. He then calculated the price per pound as $0.79. However, we need to verify if this calculation aligns with the given information.
To check if Ivan's calculation is correct, we can divide the total cost by the number of pounds purchased.
In this case, if we divide $36.57 by 4.6 pounds, we get:
$36.57 / 4.6 lbs = $7.95 per pound
Hence, the actual price per pound is $7.95, not $0.79.
Ivan's calculation was incorrect because he made an error while performing the division. The correct price per pound is significantly higher than $0.79.
