She bought 2 fancy shirts and 5 plain shirts.
2 x 28=$56, and 5x15=$75. 75 plus 56 is 131
The exponential growth function is P(t) = 6.38 million x (1.0238^t).
The population of the city in 2018 is 7.35 million.
The year the population would be 9 million is 14.46 years.
The doubling time is 29.12 years.
<h3>What is the exponential growth function?</h3>
FV = P (1 + r)^n
- FV = Future population
- P = Present population
- R = rate of growth
- N = number of years
6.38 million x (1.0238^t)
Population in 2018 = 6.38 million x (1.0238^6) = 7.35 million
Number of years when population would be 9 million : (In FV / PV) / r
(In 9 / 6.38) / 0.0238 = 14.46 years
Doubling time = In 2 / 0.0238 = 29.12 years

Answer:
X = 10/3
Step-by-step explanation:
8x - 4y = -40
y - 4x
10+2x - 4x = 10 - 2x
8(10 - 2x) -4(10 + 2x) = -40
x = 10/3
