12 lemons

Step-by-step explanation:

In this question, we are asked to find the number of lemons to be sold at a particular price to make a particular profit.

Let’s have our cost price per lemon. 3 is bought for 87 cents, that means on the average one is bought at 87/3 = 29 cents

Selling price is 2 per 0.78 , this means one is sold at 78/2 = 39 cents

Now, we need to know the number of lemons to be sold to make a profit of 120 cents.

Let the amount of lemon be x

Mathematically;

39(x) - 29(x) = 120

10x = 120

x = 120/10

x = 12

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,
