Answer 2

Calculating the Cost of One Sheet of Paper

To find the cost of one sheet of paper, we can follow these steps:

1. Calculate the number of sheets each person bought. 2. Determine the total amount spent by each person. 3. Use the information to calculate the cost of one sheet of paper.

Let's proceed with these steps.

Step 1: Calculate the Number of Sheets Each Person Bought

Lida bought 1/3 of the 120 sheets, and Irina bought 1/4 of the 120 sheets.

Lida's sheets = 1/3 * 120 = 40 sheets Irina's sheets = 1/4 * 120 = 30 sheets

Step 2: Determine the Total Amount Spent by Each Person

We know that Lida paid 5 hryvnias more than Irina. Let's denote the cost of one sheet of paper as "x".

Lida's total cost = 40x Irina's total cost = 30x

Given that Lida paid 5 hryvnias more than Irina, we can form the equation: 40x = 30x + 5

Step 3: Calculate the Cost of One Sheet of Paper

We can solve the equation to find the value of "x", which represents the cost of one sheet of paper.

40x - 30x = 5 10x = 5 x = 5 / 10 x = 0.5 hryvnias

So, the cost of one sheet of paper is 0.5 hryvnias.
