Answer:
5,040.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
A = 8000(1 + (0.07 × 9)) = 13040
A = $13,040.00
The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 7% per year for 9 years is $13,040.00.
Answer:
426 chickens
Step-by-step explanation:
let the pigs = x
the ducks = 2×x = 2x
the chickens = 3×(2x) = 6x
x +2x +6x = 639
9x=639
x = 639/9 = 71
the chickens = 6x = 6×71 = 426
9x+x=5. or 9x+x+5=0 but probably the first one
Answer:
Step-by-step explanation:
P + 4.5 = - p + 5
Bringing like terms on one side
P + p = 5 - 4.5
2p = 0.5
p = 0.5/2 = 0.25
In my opinion the answer is one solution
