A factory makes custom sports cars at an increasing rate. In the first month only one car is made, in the second month two cars are made, and so on, with n cars made in the nth month. A) Set up a recurrence relation for the number of cars produced in the first n months by this factory. B) How many cars are produced in the first year? C) Find an explicit formula for the number of cars produced in the first n months by this factory.

they would have to work 32 hours.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
