1. The problem is to find how much money Mr. Sanchez will earn after selling all the cans of Spanish sardines he can make from 43/4 kg of fish. Each can contains 1/12 kg of fish and sells for 25 pesos. 2. First, find the total kilograms of fish Mr. Sanchez has: $$\frac{43}{4} = 10.75 \text{ kg}$$ 3. Next, calculate how many cans can be made by dividing total fish by weight per can: $$\frac{10.75}{\frac{1}{12}} = 10.75 \times 12 = 129 \text{ cans}$$ 4. Now, calculate the total earnings by multiplying the number of cans by the price per can: $$129 \times 25 = 3225$$ 5. Therefore, Mr. Sanchez will earn 3225 pesos after selling all the cans.
