(a) The Feelgood Gym has a monthly membership fee of $100 and it charges an addi- tional $1 per hour. If I use the gym for x hours in a month, write down an expression
for the total cost in terms of x.
(b) Repeat part (a) for the Fabulous Me Gym, which charges $35 per month and $3.50
per hour.
(c) By plotting both graphs on the same axes, or otherwise, find the number of hours
which gives the same total cost.

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
