0.09 x + 0.1 ( x - 1500) = 610
9x + 10(x-1500) = 61000
9x + 10x - 15000 = 61000
19x = 76000
x = 4000

asked 05/03/20To save for the purchase of a new car, a deposit was made into an account that earns 9% annual simple interest. Another deposit, $1500 less than the first deposit, was placed in a certificate of deposit (CD) earning 10% annual simple interest. The total interest earned on both accounts for 1 year was $610. How much money was deposited in the CD?
