Answer:
Option (c) is correct
Problem (c) can be solved using the equation 0.15m+35=0.25m+20
Step-by-step explanation:
Given equation 0.15m + 35 = 0.25m + 20
We have to choose the correct option out of given option that can be solved using the given equation.
we solve each option and check the equation which matches with given equation.
a) Clear Check One phone company charges $35.15 per minute. The other phone company charges $20.25 per minute. For how many minutes, m, do the companies charge the same amount?
m denotes minutes.
One phone company charges $35.15 per minute that is 35.15m
other phone company charges $20.25 per minute that is 20.25m
For same amount 35.15m = 20.25m
b) One phone company charges a flat fee of $0.15, plus $35 for each minute. The other phone company charges a flat fee of $0.25, plus $20 for each minute. For how many minutes, m, do the companies charge the same amount?
One phone company charges a flat fee of $0.15, plus $35 for each minute that is 0.15 + 35m
other phone company charges a flat fee of $0.25, plus $20 for each minute that is 0.25 +20m
For same amount 0.15 + 35m = 0.25 + 20m
c) One phone company charges a flat fee of $35, plus $0.15 for each minute. The other phone company charges a flat fee of $20, plus $0.25 for each minute. For how many minutes, m, do the companies charge the same amount?
One phone company charges a flat fee of $35, plus $0.15 for each minute that is 35 + 0.15m
other phone company charges a flat fee of $20, plus $0.25 for each minute that is 20 + 0.25m
For same amount 0.15m+35=0.25m+20
Thus, option (c) is correct
problem (c) can be solved using the equation 0.15m+35=0.25m+20
