Answer:
Step-by-step explanation:
t1 = a1
t2 = a1 + d
t3 = a1 + 2d
The sum is t1 + t2 + t3 = a1 + a1 + d + a1 + 2d = 3a1 + 3d
Second question
t1 = a1
t2 = a1 + d
t3 = a1 + 2d
t4 = a1 + 3d
...
tn = a1 + (n - 1)*d
Sum = (a1 + a1 + (n- 1)*d) * n / 2
Sum = (2a1 + nd - d) * n / 2
Sum = (2a1*n + n^2*d - nd) / 2
The answer: x=857 and y=-401
Set up the two equations
X+2y=55
2x+y=1313
Solve the system of equations by elimination
2x+y=1313
-2x-4y=-110
Add each of the corresponding terms together
-3y=1203
Divide by -3
Y=-401
Plug y back into one of the original equations
X+2(-401)=55
X-802=55
X=857
Answer:
the final amount value is $4,274.58
Step-by-step explanation:
Given that
Present value = $3,500
Time period = 5 × 52 = 260
Rate of interest = 4% ÷ 52 = 0.0769%
We need to determine the final amount i.e. future value
So as we know that
Future value = Present value × (1 + rate of interest)^time period
= $3,500 × (1 + 0.0769%)^260
= $4,274.58
Hence, the final amount value is $4,274.58
