Answer:
10
Step-by-step explanation:
Suppose he invest x dollars in one account, y in the other
x+y=12,500
0.042x+0.062y=669.50
multiple the first equation by 0.042: 0.042x+0.042y=525
subtract this new equation from equation 2: 0.02y=144.50
y=7225
x=12500-7225=5275
Answer:
5(y / 7)
Step-by-step explanation:
A quotient is the answer to a division problem. This tells us that y and 7 are being divided.
We have (y / 7) so far.
Five times this quotient (y / 7) can be represented by 5*, as the quotient is being multiplied by 5.
The final expression can be shown as: 5(y / 7).
