t = - 6.25 In ( 1 N over 80) according to the formula what is the maximum number of word per minute. Round off to the nearest whole number. Solve N
To find the maximum number of words per minute, we need to solve for N in the equation:
t = -6.25 * ln(1 N/80)
To solve for N, we need to isolate it on one side of the equation. Here are the steps:
1. Divide both sides of the equation by -6.25:
t / -6.25 = ln(1 N/80)
2. Rewrite the equation using exponential form:
e^(t / -6.25) = 1 N/80
3. Multiply both sides of the equation by 80:
80 * e^(t / -6.25) = N
Now that we have the equation in terms of N, we can substitute the given value of t to find the maximum number of words per minute:
t = -6.25
N = 80 * e^(-6.25 / -6.25)
Simplifying further:
N = 80 * e^1
N = 80 * 2.71
N ≈ 217
Therefore, the maximum number of words per minute, rounded to the nearest whole number, is 217.
