An investor invests a total of $15,000 in two banks. One bank pays 4% simple interest, and the other bank pays 2.5% simple interest. The investor earns $472.80 annual interest. Set up a system of equations to represent this relationship with x= the amount invested at 4% and y = the amount invested at 2.5% How much was invested at 2.5%?

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

false
