Question

a computer shop charges 20p per hour (or a fruction of an hour) for the first two hours and an additional 10 pesos per hour for each succeeding hour represent your computer rental fee using the function R(t) where t is the number of hours you spend on the computer.

Answer 1

Answer with explanation:

Amount charged by computer shop for first two hours = 20 p per hour

Amount Charged for each succeeding hour = 10 p per hour

If you spend , t hours on the computer, then total amount spend in terms of R(t), is given by

If we divide ,total time t, such that

t = t-2 +2

Then, R(t)= 2 × 20 p + 10 p × (t-2)

R(t)=40 p+ 10 p t -20 p

   = 2 0 p +10 p t

R(t)= (20 +10 t) p
