I wpuld say B...because that can be the one Delta planet
50+0.05x-25=20+0.06x-12
Solve algebraically <span />
Answer:
$2,833.47
Step-by-step explanation:
n = [lnA - lnP] / ln(1 + i)
n = [ln15000 - ln10000] / ln(1 + 0.03)
n = [9.6158 - 9.2103] / 0.0296
n = 13.70
13 years, 8 months and 12 Days
Part 2:
P = A / [(1 + i)n]
P = 15000 / [(1.03)4]
P = 15000 / 1.1255
P = $13,327.31
Part 3:
A = 10000 (1 + 0.04)5
A = $12,166.53
The amount of money you need to save to buy a car at $15,000 would be;
$15,000 - $12,166.53
=> $2,833.47
Answer:
<em>about 9765 mosquitoes</em>
<em />
Step-by-step explanation:
This is an exponential growth problem which follows the formula:

Where A is the future amount (we need this after 4 months)
P is the initial amount (here, it is 4000)
r is the rate of increase (here it is 25% or 0.25)
t is the time period (here t= 4, because we want to know after 4 months)
<em>plugging in all the available/given info, we can solve for A:</em>
<em>
</em>

<em>Since, no fractional mosquitoes, we round down to </em><em>9765 mosquitoes</em>
