5000*0.03+0.05x=275
Solve for x
X=2500
The answer is b

Answer:

B

Step-by-step explanation:

If the is is a fixed interest for a year, let x be the amount invested at 5%. an expression can be written as:

[tex]5000\cdot{0.03}+x\cdot{0.05}=275[/tex]

[tex]0.05\cdot{x}=275-150[/tex]

[tex]x=125/0.05=2500[/tex]

The amount that must be invested is $2500. The answer is B.
