Answer:
Step-by-step explanation:
use the distributive propriety to get 4c -12 = 8
divide both sides by 4 to get c-3 =2
First find the amount of each payment:

The total cost will be 40 payments plus service charges.

The percentage is the service charge divided by total cost:
Answer:
10 cm³
Step-by-step explanation:
The equation for density is: d = m/v, where d is the density, m is the mass, and v is the volume.
Here, d = 2.5 and m = 25.0, so plug these into the equation to solve for v:
d = m/v
2.5 = 25/v
Multiply both sides by v:
2.5v = 25
Divide by 2.5:
v = 25/2.5 = 10
Thus, the volume is 10 cm³.
