About 7.1 Lol. Arrrrg needs to be 20 charecters long is it yet
Answer:
15% = $5100
7% = 900
Step-by-step explanation:
With simultaneous equations we can take the easier number like numbers that end in 0 or 5 or 2 etc.
We have 7% which is a prime and 15 so we call and name 'x' = amount
invested at 15%
x = the amount invested at 15%
Then 6000-x = the amount invested at 7%
The total interest earned is $710.
Therefore solve the simultaneous equation by substituting the 6000-x
0.15x + 0.08 (6000-x) = 710
Solve for x:
0.15x - 0.07x + 353 = 780 -> x = 357/0.07= $5100
Therefore the amount invested at 7% interest = 6000 - 5100 = $900
and here, 6000-900 = 5100 = 15%
