Answer:
big
Step-by-step explanation:
2
A = 115 + 1/2 (p + s)
you subtract 115 from both sides, and you get
A - 115 = 1/2 (p + s)
now you multiply by 2 on both sides, and you get
(A - 115) * 2 = p + s
NOTE: I DISTRIBUTED 2 IN THE FOLLOWING EQUATIONnow you subtract p on both sides to get s by itself and you get
2A - 230 - p = s
so the final answer is .......
35 + 0.05m = 50 + 0.01m <== ur equation
0.05m - 0.01m = 50 - 35
0.04m = 15
m = 15/0.04
m = 375.....u need to send 375 text messages for the plans to be equal
