Answer:
Cost of staying hotel with fixed charge of 50 and $6 for each day stay
where d is number of days of stay
M is total money charged by hotel.
Step-by-step explanation:
We have to describe a situation to fit into the given model.
model is M = 50 + 6d
it consist of two part
constant part 50
and variable part 6d which depends on value of d,
Let take M as money
d as days
in hotel, hotel service charge is fixed at 50
and for each day stay 6$ is charged.
Thus,
total money charged by hotel will be equal to sum of
fixed part 50
$6d for staying d days in the hotel
which can be modeled by given equation
M = 50 + 6d
