C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit
The increase in miles would be 11 miles
PV × (1 + r/n)∧nt = FV
$70.00 × (1 + .16/4)∧4X25 = FV
$70.00 × (1 + .04)∧100 = FV
$70.00 × 50.50 = FV
$3535 =FV
The final amount is $3535
Answer:
Her potential energy is approximately 4481 J.
Step-by-step explanation:
Because the formula for potential energy is PEg = 9.81 * mass * height, just plug in the knowns. After you plug those in, you will get the potential energy as 9.81 * 450, which is approximately 4481 J.
