your cousin borrow 5000 at an interest rate of 7.5% and the rest at an interest rate of 12% the total paid is 819 . how much did your cousin borrow at each rate
.075x + .12(5000-x) = 819
To find out how much your cousin borrowed at each interest rate, we can set up a system of equations.
Let's assume your cousin borrowed an amount (in dollars) at a 7.5% interest rate and the remaining amount at a 12% interest rate.
Let's say the amount borrowed at a 7.5% interest rate is x, and the amount borrowed at a 12% interest rate is y.
We can set up the following equations based on the given information:
Equation 1: x + y = the total amount borrowed
Equation 2: (0.075 * x) + (0.12 * y) = 819
Now, let's solve this system of equations to find the values of x and y.
From Equation 1, we know that x + y = the total amount borrowed. However, we don't have this information in the question. Could you please provide the total amount borrowed?
