The formula is
A=p (1+r)^t
A future value 8000
P present value?
R interest rate 0.05
T time 3years
Solve the formula for p
P=A÷(1+r)^t
P=8,000÷(1+0.05)^(3)
P=6,910.70
Hope it helps!
The alloy contains 10.5 pounds of copper.
Px - 45 = QX + 75
Px - Qx = 75 + 45 = 120
A. If P = - 45 and Q = - 75, then
- 45x + 75 x = 120
30x = 120 and x = 40
B. If P = 45 and Q = - 15, then
45x - 15x = 120
30x = 120
x = 40
D. If P = 15 and Q = 75, then
15x - 75x = 120
- 60x = 120
x = - 2
C. If P = 15 and Q = 15, then
15x - 15x = 120
0 = 120 which is absurd.
Hence, P = 15 and Q = 15 result in an equation with no solution.
Answer:
x +16 = 118
Step-by-step explanation:
A number(unknown ) = x
Increased = +
Merge all together you have

Tip ; If you solve the equation you will get 102 as an answer. 102 +16 =118 .
SO the equation is correct .☻
