Answer:
Step-by-step explanation:
Answer:
P = $ 482.00
Equation:
P = I / rt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
P = 72.3 / ( 0.05 × 3 ) = 482
P = $ 482.00
The principal required to
accumulate interest of $ 72.30
on a rate of 5% per year for 3 years is $ 482.00.

Answer:
29/59
Step-by-step explanation:
2x + y = 20
y = 20 - 2x
Substitute into second equation:
6x - 5(20-2x) = 12
6x -100 +10x = 12
16x = 112
x = 7
Plug back into first equation:
2(7) + y = 20
14 +y = 20
y = 6
Answer is x = 7 and y = 6
