Answer: $ 234
Step-by-step explanation:
Given: The selling price of 1 kg cumin = $7.20
Then, the selling price of 90 kilograms of cumin = [tex]90\times7.20=[/tex]
Thus, the selling price of 90 kilograms of cumin =[tex]\$648[/tex]
The net profit on selling 90 kg of cumin = $414
We know that Profit = Selling price -Expenses
⇒ Expenses=Selling price -Profit
⇒Expenses=[tex]\$648-\$414[/tex]
⇒Expenses[tex]=\$234[/tex]
Therefore, Alexandra's weekly expenses=$ 234
