"The perimeter P..." gives us one variable to work with.
"is" in this context almost always means "equals".
"the sum" we know we will be adding.
"twice the length l" gives us a variable and a coefficient.
"twice the width w" gives us a variable and a coefficient.
The equation for this is P=2l+2w
I hope in the future you can remember these tips! :)

Answer:
The amount invested in the mutual fund that earned 5% was $1,000
The amount invested in the mutual fund that earned 3% was $1,800
Step-by-step explanation:
Let
x ----> the amount invested in the mutual fund that earned 5%
y ----> the amount invested in the mutual fund that earned 3%
we know that
---->
----> equation A


----> equation B
Solve the system by substitution
substitute equation A in equation B
Solve for x

<em>Find the value of y</em>


therefore
The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800
