Can you please help me with these two word problem-examples? (Rental Charge)
1) The charge C for renting an air hammer from Taylor Rentals is a linear function of the number n of days in the rental period. The charge is $113 for two days and $209 for for five -days. Write C as a linear function of n. What would the charge be for five days??
(Probabilty of Rain)
(2) When the probability p of rain is 90%, the probability of q that it does not rain is, 10%. When the probabilty of rain is 80%, then the probabilty that it does not rain is 20%.
I need to know exactly how to break these problems down and if you could explain in detail steo by step for this process, I just don't get it???
A linear function is always written in teh form f(x) = ax + b, where a and b are constants to be determined.
<br>Here we have C(n) = an + b
<br>For n = 2, C(2) = $113
<br>Therefore, 113 = 2a + b ....(i)
<br>For n = 5, C(5) = $209
