Answer 3

Calculation of the Price Difference

To calculate the price difference between the chocolate bar and the "Gulliver" candies, we can set up a system of equations based on the given information.

Let's assume that the price of the chocolate bar is represented by x rubles, and the price of one "Gulliver" candy is represented by y rubles.

According to the information provided, we have the following equations:

Equation 1: x + y = 18 (The chocolate bar and one "Gulliver" candy together cost 18 rubles)

Equation 2: 5y + x = 50 (Five "Gulliver" candies and the chocolate bar together cost 50 rubles)

To find the value of x (the price of the chocolate bar) in terms of y (the price of one "Gulliver" candy), we can solve this system of equations.

Solving the System of Equations

Let's solve the system of equations using the substitution method:

From Equation 1, we can express x in terms of y:

x = 18 - y

Substituting this value of x into Equation 2:

5y + (18 - y) = 50

Simplifying the equation:

4y = 32

Dividing both sides by 4:

y = 8

Now that we have the value of y, we can substitute it back into Equation 1 to find the value of x:

x + 8 = 18

Simplifying the equation:

x = 10

Conclusion

Therefore, the price of the chocolate bar is 10 rubles, and the price of one "Gulliver" candy is 8 rubles.

To find the price difference between the chocolate bar and the "Gulliver" candy, we can subtract the price of the candy from the price of the chocolate bar:

Price difference = x - y = 10 - 8 = 2 rubles

Thus, the chocolate bar is 2 times more expensive than the "Gulliver" candy.
