Calculating the Amount of Rice Sent to the Store and Kindergartens

To calculate the amount of rice sent to the store and kindergartens, we can use the following steps:

1. Calculate the total amount of rice at the warehouse. 2. Determine the amount of rice sent to the store and kindergartens. 3. Use the given information to find the amount of rice sent to the store and kindergartens.

Step 1: Calculate the Total Amount of Rice at the Warehouse

The total amount of rice at the warehouse is 2.8 tons.

Step 2: Determine the Amount of Rice Sent to the Store and Kindergartens

Let's denote: - Total amount of rice at the warehouse as R - Amount of rice sent to the store as S - Amount of rice sent to kindergartens as K

Given: - S + K = 0.7R (70% of the total rice was sent to the store and kindergartens) - S - K = 1.48 (the amount sent to the store is 1.48 tons more than the amount sent to kindergartens)

Step 3: Use the Given Information to Find the Amount of Rice Sent to the Store and Kindergartens

We can solve the system of equations to find the values of S and K.

Using the substitution method, we can solve for S and K: - From the equation S - K = 1.48, we can express S as S = K + 1.48. - Substitute S = K + 1.48 into the equation S + K = 0.7R to solve for K.

Let's calculate the values of S and K using the given information.

Solving for K: - Substitute S = K + 1.48 into the equation S + K = 0.7R: - (K + 1.48) + K = 0.7(2.8) - 2K + 1.48 = 1.96 - 2K = 1.96 - 1.48 - 2K = 0.48 - K = 0.24

Solving for S: - Using S = K + 1.48: - S = 0.24 + 1.48 - S = 1.72

Conclusion:

- The amount of rice sent to the store is 1.72 tons. - The amount of rice sent to kindergartens is 0.24 tons.
