You invest $850 into a stock market fund, which grows at a rate of approximately 4% each year. Write an equation that can be use
SCORPION-xisa [38]

We have been given that you invest $850 into a stock market fund, which grows at a rate of approximately 4% each year. We are asked to write an equation that can be used to calculate the amount of money in the fund after x years.

We will use exponential growth formula to solve our given problem.

An exponential function is in form y=a\cdot (1+r)^x, where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

Let us convert 4% into decimal.

4\%=\frac{4}{100}=0.04.

We have a=840 and r=0.04, so our equation would be:

y=850\cdot (1+0.04)^x

y=850\cdot (1.04)^x

Therefore, the equation y=850\cdot (1.04)^x can be used to calculate the amount of money in the fund after x years.

An example of a direct variation scenario is the increase in the income of a start-up bakeshop when the number of cakes sold increase. Example data are (4, $ 100), (5, $ 125), (6, $ 150), and (7, $ 175). 

The example of indirect variation scenario is the decrease in time it takes to reach a destination when the speed of the mobile increases. This is shown in the data points: (10 kph, 10 mins), (12 kph, 8 mins), (14 kph, 6 mins), and (16 kph, 4 mins).

Top left:
7x-44 = 4x+4
7x-4x = 4+44
3x = 48
x = 16
8y-43 = 39+(7(16)-44)
8y = 39+68+43
8y = 150
y = 18.75
