Answer:
The answer should be 1500g I think.
Answer:
To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative.
Answer:
$1799
Step-by-step explanation:
We simply work backwards and write out an equation.
Lets call the initial price P.
First we have 15% off the initial price P which means that we are only paying 85% of the initial price: .85*P.
Next we use a coupon for 20% off the reduced price which means we only pay 80% of the reduced price: .80 * (.85 * P)
We know that the price paid was $1223.32, set that equal to .80 * (.85 * P)
and we find that P is $1799
Exponential growth function is given by f(t) = A(1 + k%)^t; where A is the initial value, k is the growth rate and t is the time period.
Therefore, the required function is
f(t) = 120,000(1 + 0.012)^t = 120,000(1.012)^t
After 15 years, the new population is 120,000(1.012)^15 = 120,000 x 1.1959 = 143,512
I think:
from 2013 to 2025 are 12 years
so the percent will increase: 1.1 x 12= 13.2%
population in 2025: (100%+13.2%)x 7.1= 8.0372 billion people
