Question 951827
Let’s call the amount on the account that pays 8% “a” and the account making 6% “b” (I do this instead of using x and y because I like being able to use x as a multiplication sign):

There are two amounts in question:

a: pays .08 per each dollar, or 8 percent (means 8 for every hundred). We want to calculate per each dollar, so we’ll use .08
b: equals a + 900, so the amount that pays 6% is .06(a) + .06(900)

.08a + .06a + (.06 * 900)= 124  Multiply and add on left:
.14a + 54 = 124 Subtract 54, both sides:
.14a = 70 Divide both sides by .14
a = 500
b = 500 + 900 = 1,400
So there’s your answer. One savings account has 1,400 and pays 6% and the other has 500 and pays 8%
