Calculation of the Cost of Sugar Packets

To calculate the cost of one sugar packet for a regular customer who has been shopping at the store for several years, we need to consider the following information:

- The price of one sugar packet in the store is 50 rubles. - Each purchased packet contains a coupon. - By collecting 8 coupons, a customer can get one free sugar packet.

To determine the cost of one sugar packet for the regular customer, we need to calculate how many packets they need to purchase to collect 8 coupons.

Let's assume the regular customer purchases 'x' packets of sugar. Since each packet contains a coupon, the number of coupons collected will be equal to 'x'.

To calculate the number of free sugar packets the customer can get, we divide the number of coupons collected by 8:

Number of free sugar packets = x / 8

To calculate the total cost of the purchased sugar packets, we multiply the number of purchased packets by the price of one packet:

Total cost of purchased sugar packets = x * 50 rubles

Since the customer receives one free sugar packet for every 8 purchased packets, the total number of sugar packets the customer will have is:

Total number of sugar packets = x + (x / 8)

To calculate the cost of one sugar packet for the regular customer, we divide the total cost of purchased sugar packets by the total number of sugar packets:

Cost of one sugar packet for the regular customer = (x * 50 rubles) / (x + (x / 8))

Now, let's calculate the cost of one sugar packet for the regular customer.
