Answer:
$16000 invested in 4.25% and 16000 invested in 6.25%
Step-by-step explanation:
Let x be the amount invested in 4.25% and y be the amount invested in 6.25%
4.25%= 0.0425
6.25%= 0.0625
subtract x from both sides
total interest earned is 1680
Now solve for x and y
subtract 2000 from both sides
divide by -0.02 from both sides
x=16000
Answer:
The value of <em>x</em> is 0.624.
Property used: Symmetric property of equality
Step-by-step explanation:
The expression to be solved is:
Compute the solution as follows:
∵ Distributive property (a (b + c) = ab + ac)
Substitute equation equal to 0 to compute the value of <em>x</em> as follows:
∵ Symmetric property of equality if a = b then b = a
Thus, the value of <em>x</em> is 0.624.
