1 decade = 10 years
30 years = 3 decades
Simply plug in the value of the number of decades needed to find into where the x value is.
<span>f(x) = 5000 · 2^x
</span><span>f(3) = 5000 · 2^3 = 40000
The investment is worth $40000 after 30 years.

Remember the equation to find the circumference?
Equation of circumference: Pi x 2(radius)
Therefore, 3.141592654 x 2(6ft) = 37.7 feet
Answer:
Supermarket gets 300 cupcakes.
Step-by-step explanation:
Given,
Total cupcakes = 525,
Since, the ratio of bakery and supermarket cupcakes = 3 : 4,
Let the bakery cupcakes = 3x and supermarket cupcakes = 4x
Where x is any positive real number.
So, the total cupcakes = 3x + 4x = 7x
Divide both sides by 7,
Hence, the supermarket cupcakes = 4(75) = 300
