The equation would look something like this: 50+60x (x being the number of hours the plumber worked)
Since the price increases by $60 every hour, the constant rate would be $60. The total cost of the bill would be 50+60*6
( $410 )
R = 55 total reservations - 5 reservations from the last hour / 5 hours
R = 55 -5 / 5
r = 10
Well, for 20 you just add them, to get
. For 21, you do a substraction:
. It'd take him quite some time (does this one even have zeros? :)) )
Price before membership= price 1 = $6
price after membership = price 2 = $4
Membership price = $100
SO according to price 1 and price 2; price after membership saves up $2 for each session.
Hence to justify the price of membership number of sessions can be calculated as follows:-
$2 saved = 1 session
to make it $100 multiply both sides by 50
2×50 = 1×50
100$ saved = 50 sessions
so 50 sessions ate required to justify buying the membership.
Hope this helped :)
