Answer:
The final balance is $7,913 and the total compound interest is $413.27
To calculate compound intrest, you need to multiply the initial principal amount ($7500) by one , plus the annual intrest rate (2.7%) raised to the number of compound periods minus one. The total initial amount of the loan is the subtracted from the resulting value.
X= 2 bed rooms
y= 3 bed rooms
Adding x+y will equal the total number of rooms (40). Multiplying (2 beds * the number of 2 bed rooms) and (3 beds * the number of 3 bed rooms), and adding those together, will equal the total number of beds (92).
x+y= 40 rooms
2x+3y= 92 beds
Solve for one variable in equation one and substitute it in equation two.
Solve for one variable:
x+y= 40
Subtract y from both sides
x= 40-y
Substitute (40-y) in for x in equation two:
2x+3y= 92
2(40-y) +3y= 92
80-2y+3y=92
Subtract 80 from both sides
y= 12 three bed rooms
Substitute 12 in for y in either equation:
x+y= 40
x+12= 40
x= 28 two bed rooms
Check work:
2x+3y= 92
2(28)+3(12)= 92
56+36= 92
92= 92
Hope this helps! :)
In order to estimate this problem we must first estimate the two numbers involved.
137,638 rounds up to 138,000.
Since the 6 is bigger than 5 it makes the number 7 round up to 8
Now..
52,091 rounds out to 52,000
Since the number to the left of the 2 is not bigger than 5 then it stays the same at 52,000
Now we have to add our estimated numbers.
138,000 + 52,000 = 190,000
Your answer is 190,000
Good Luck! :)

</span>2 Cancel 2x on both sides.
<span>20<17
</span>3 Since <span>20<17</span> is false, there is no solution<span>
No solution. :)
I hope this helps you understand! :D
Have a great day by the way.
