Answer: -13
Step-by-step explanation:
just substitute the letters for the numbers.
5(-2) - 3(2) -(-3)
then, remove the parenthesis.
-10 - 6 + 3
finally, just calculate it.
-13
Let amount invested at 8% per year = x
Let amount invested at 14% per year = y
Total investment is $94000 then we get equation:
x+y=94000
or
x=94000-y...(i)
Given that total return in 1 year is $8720 so we can write equation:
8% of x + 14% of y = 8720
or
0.08x+0.14y=8720...(ii)
plug (i) into (ii)
0.08(94000-y)+0.14y=8720
7520-0.08y+0.14y=8720
7520+0.06y=8720
0.06y=8720-7520
0.06y=1200
y=20000
plug value of y into (i)
x=94000-y=94000-20000=74000
Hence final answer is given by:
Amount invested at 8% per year = $74000
Amount invested at 14% per year = $20000
