Keimia grows and sells kiwis. She sells 206 kiwis in January, 252 kiwis in February and 161 kiwis in March. The kiwis are priced by weight, with an average price of £0.22 per kiwi. Keimia uses the following calculation to estimate how much money she has made:
(Total number of kiwis) x (Price per kiwi) = (200 + 250 + 150) x (0.20) = £120
Is Keimia's estimate likely to be higher or lower than the actual amount of money she made? Explain your answer.
Keimia's estimate is likely to be lower than the actual amount of money she made. The reason is that the price per kiwi used in her estimate is £0.20, while the actual price per kiwi is £0.22. This means that for each kiwi sold, she would actually make £0.02 more than what was used in the estimate. Multiplying the actual price per kiwi by the total number of kiwis sold would result in a higher amount of money made compared to the estimate.
