Nina [5.8K]
We are given an equation <span> f(n) = 15(1.04)^n where f(n) is the plant height in cm and n is the number of days since the day planted. The domain of the plant is a set including 0 to positive infinity. The y-intercept of the graph is when n = 0 or equal to 15. when n is 1, f(n) is equal to 15.6 . when n is 5, f(n) is equal to 18.25. the rate of change is (18.25-15.6)/(5-1) equal to 0.66</span>

Answer:

0.6x = 87

Step-by-step explanation:

Hi, to answer this question we have to write en equation:

We have to multiply the variable x by the percentage given (60%) in decimal form (divided by 100). That expression must be equal to 87.

Mathematically speaking:

x (60/100) = 87

0.6x = 87
