Do you know how to solve simultaneous equation?
Anastasy [175]3 years ago
3 0
9x + 5y = -154
4x + y = -22

9x + 5y = -154
20x + 5y = -110 (x5)

Then minus the bottom one from the top one, so at least one of the variables (x or y) cancel out, then you are left with : -11x = -44

Then solve :
-11x = -44
x = 4

Then put -4 back into x, into any of the first two equations

4(4) + y = -22
16 + y = -22
y = -38

How many days would it take a construction loan of $548,048 to earn $50,000 exact interest at 9% interest rate?
storchak [24]
This is the concept of commercial arithmetic, to solve for the time taken for loan of $548,048 to earn an interest of 50,000 given an interest rate of 9%. We use the formula:
A=P(1+r/100)^n
Where;
A=Future amount=548,048+50000=$598,048
P=principle
r=rate
n=time
thus;
598,048=548048(1+9/100)^n
1.0912=(1+0.09)^n
getting the logs of both sides
ln 1.0912=n ln1.09
thus
n=(ln 1.0912)/(ln 1.09)
n=1.01 years
The answer is 1 year
