14h = c
If c = the total cost, then the equation should end with "= c" because we're trying to find the total cost of renting a row boat.
If the row boat is $14 per hour, that's 14 x hours, or 14h.
Therefore, 14h = c.
Hope this helps!
Answer:
$4,027.51
Step-by-step explanation:
Use the formula P*e^(r * t)
P = principal amount
e = the constant e
r = rate
t = time, in years
2,000 * e ^ (0.07 * 10)
2,000 * e ^ (0.7) ≈ 4,027.51
The answer is 4 hours
p -<span> the programming time
</span>c - time spent on commercials
<span>A radio station broadcasts programs and commercials 20 hours everyday:
p + c = 20
</span><span>The ratio of the time spent on commercials to the programming time is 1:4.
c : p = 1 : 4
p = c * 4 : 1
p = 4c
p + c = 20
p = 4c
_____
4c + c = 20
5c = 20
c = 20 : 5
c = 4h</span>
