Answer 2

Problem Analysis

To solve this problem, we need to calculate the total cost of four movie tickets on a Thursday. The ticket price on weekends is 300 rubles, while on weekdays it is 30% lower. We'll calculate the cost of four tickets on a Thursday.

Calculation

The ticket price on weekdays is 30% lower than the weekend price of 300 rubles. To find the weekday ticket price, we'll subtract 30% of 300 rubles from 300 rubles.

Weekday ticket price = 300 rubles - (30% of 300 rubles)

To calculate 30% of 300 rubles, we'll multiply 300 by 0.3.

Weekday ticket price = 300 rubles - (300 rubles * 0.3)

Now, we'll calculate the cost of four tickets on a Thursday by multiplying the weekday ticket price by four.

Total cost of four tickets on a Thursday = Weekday ticket price * 4

Let's calculate the answer.

Calculation Steps

1. Calculate 30% of 300 rubles: 300 rubles * 0.3 = 90 rubles. 2. Subtract 90 rubles from 300 rubles: 300 rubles - 90 rubles = 210 rubles. 3. Multiply 210 rubles by 4: 210 rubles * 4 = 840 rubles.

Answer

The total cost of four movie tickets on a Thursday will be 840 rubles.
