Calculation of the Weekly Cost of Cat Food

To calculate the difference in the cost of the weekly cat food supply before and after the price reduction, we need to determine the cost of the cat food before the discount and after the discount.

Given: - The original price of one packet of cat food was 6 rubles. - The current price of one packet of cat food is 6 rubles, which is 3/4 of its previous price.

To calculate the original price of one packet of cat food, we can use the equation:

Original price = Current price / (3/4)

Substituting the given values:

Original price = 6 rubles / (3/4) = 8 rubles

Now, we can calculate the weekly cost of cat food before and after the price reduction.

Before the price reduction: - The cat consumes 21 packets of cat food per week. - The original price of one packet of cat food is 8 rubles.

Weekly cost before the price reduction = Number of packets consumed per week * Original price per packet

Substituting the given values:

Weekly cost before the price reduction = 21 packets * 8 rubles = 168 rubles

After the price reduction: - The cat consumes 21 packets of cat food per week. - The current price of one packet of cat food is 6 rubles.

Weekly cost after the price reduction = Number of packets consumed per week * Current price per packet

Substituting the given values:

Weekly cost after the price reduction = 21 packets * 6 rubles = 126 rubles

Answer:

The weekly cost of cat food after the price reduction is 126 rubles. This is 42 rubles less than the weekly cost before the price reduction, which was 168 rubles.
