Let
x--------> the number of sessions
y-------> the total payment
we know that
without membership:
--------> equation
with membership:
--------> equation
using a graph tool------> resolve the system of equations
see the attached figure
the solution is the point
that means
For
the cost is in both forms
so
to justify buying the membership
therefore
<u>the answer is</u>
The flat fee that the store charges is $14 and the cost for 7 hours is $56
A linear equation is on the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
let f for the total rental cost of a vacuum cleaner for x hours
Using the points (1, 20) and (3, 32) from the table:
The flat fee that the store charges is $14
The reasonable domain is 1 ≤ x ≤ 12
The cost for 7 hours is:
f(7) = 6(7) + 14 = 46
