Answer:
you first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

The percentage change from 300 to 375 is 25 %
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((375 - 300) / 300) * 100 = 25 %
Answer:
m=a/x+Q
Step-by-step explanation:
Q=m-a/x
To solve this we need to isolate m so we will bring -a/x to the other side of the equal sign so it will become positive i.e. ax now will be written as a/x+Q=m
in other wards m=a/x+Q
Answer:
$110
Step-by-step explanation:
So first you have to do 15*4. We get the 4 from the admission fees and the 15 from the number of dances they attend. From this answer we can see the total of money they will be paying for admission for the 15 dances.
15*4=$60
However, our answer isn't just $50 as we are also told membership costs $50. So no we add $50 to $60, which gives us an answer of $110, which is the amount the member will pay if they attend 15 dances during the school year.
