The zonda information and telephone company (zi& t) calculates a customer’s total monthly cell phone
charge using the formula,
c = (b + rm)(1 + t),
where c is the total cell phone charge, b is a basic monthly fee, r is the rate per minute, m is the number
of minutes used that month, and t is the tax rate.
solve for m, the number of minutes the customer used that month.

The answer of the following question is m = \frac{C - b - bt}{r + rt}.

Solution:

C = (b + rm)(1 + t),

C = b + rm + bt + rmt

C = b + bt + rm + rmt

C - b - bt = m (r + rt)

\frac{C - b - bt}{r + rt} = m

t\neq -1,  

r\neq 0

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
