Write your values for a, b, and c at the top of your paper and follow all the instructions. 15 b= 12 с c=15 Taika invested a total of $ (a + b + c + 900) x 1,000 into three investment accounts, payis 3%,4%, and 5% simple interest per year. The annual interest earned on the three investmem was $ (c + 720) x 50. Twice as much money is invested at 3% as invested at 5%. Let x be the amount invested in the 3% account, y be the amount invested in the 4% accou and z be the amount invested in the 5% account. (a) Use the given information to write a system of linear equations for x, y, and z.
