Question

Maria, Isabel, and Lizbeth Velazquez are pooling their money to start a new restaurant. The total investment is $1,400,000, and the investments are in the ratio of 6:9:10. How much money did each sister individually invest in the restaurant?

Answer 1

Let x represent the amount of money Maria invested, y represent the amount of money Isabel invested, and z represent the amount of money Lizbeth invested. According to the given ratio, we can set up the equation 6x + 9y + 10z = 1,400,000. From there, we can solve for one variable in terms of the other two and express the individual investments using any combination of two variables.

Step-by-step explanation:

Let's represent the amount of money each sister invested as follows:

Let x represent the amount of money Maria invested.

Let y represent the amount of money Isabel invested.

Let z represent the amount of money Lizbeth invested.

According to the given ratio, we can set up the following equation:

6x + 9y + 10z = 1,400,000

Since there are no additional constraints, we can't determine the exact individual investments. However, we can solve for one variable in terms of the other two and express the individual investments using any combination of two variables.
