The number is assumed to be x
x of 40% = 56
x * (40/100) = 56
x = 5600 / 40
x = 140
Answer:
x = 1
Step-by-step explanation:
Expand brackets
2x + 16 - 4x = 10x + 4
Rearrange so that x's are on one side and whole numbers are on the other
2x - 4x - 10x = 4 - 16
Simplify
-12x = -12
Make x on its own
x = 1

Infinitely Many Solutions because is you simplify either one, you get the same equation as the other.
Answer:
$1,250
Step-by-step explanation:
You can find the answer using the following formula:
i = Prn
i= interest= $400
P= principal
r= rate of interest=0.04
t= time periods= 8
You can replace the values you have in the formula and then, isolate P:
400= P*0.04*8
400=P*0.32
P= 400/0.32
P= 1250
According to this, the answer is that Anna borrowed $1,250.
