Table is attached below
From the table we can see that the Lemon cost is equal to 35% of the expenses
Let the expense be x, Lemons cost is 70
Lemon cost = 35% * x
70 = 35% * x ( 35% = [tex] \frac{35}{100} [/tex] = 0.35)
70 = 0.35 * x
x = [tex] \frac{70}{0.35} [/tex]
x= 200, Expense = $200
Given : Profit percentage is 15%= [tex] \frac{15}{100} [/tex] = 0.15
Profit = profit percentage * Expense
Profit = 0.15 * 200 = 30
So profit = $30
