Amarathon runner will donate $5000 to charity if her time is less than or equal to 3 hours. she will donate $2000 if her time is more than 3 hours but less than or equal to 4 hours. finally, she will donate $1000 to charity if her time is more than 4 hours.
a. write a piecewise function describing this situation.

Step-by-step explanation:

Let x represents the number of hours and f(x) represents the amount ( in dollars ) of donation for x hours,

Given,

for x ≤ 3,

f(x) = 5000,

For 3 < x ≤ 4,

f(x) = 2000,

For 4 < x,

f(x) = 1000,

∵ Number of hours can not be negative,

⇒ x ≥ 0

Hence, the required function is,

10 you would take 50/ .2
