Answer:
2. [tex]25x+30=y[/tex]
Step-by-step explanation:
Let y be the total cost for gym membership.
It have been given that your gym membership costs $30 to join and $25 per month. This means that $30 is constant value of our equation and 25x will be the cost for a membership that will last for x days.
We can write an equation that gives the total cost for a membership of x days by equating y with sum of joining charges and cost of membership for x days : [tex]y=25x+30[/tex]
Now let check which of the given choices is correct.
1. [tex]25x?30=y[/tex]
In our first option sign between 25x and 30 is not clear, therefore, our first option is not correct.
2. [tex]25x+30=y[/tex]
Upon looking at our given choices we can see that expression represented by 2nd option is exactly same as our expression, therefore, 2nd option is the correct choice.
3. [tex]25x=30y[/tex]
We can see that constant value ($30) in being multiplied by total cost(y), therefore, our 3rd option is not a correct choice.
4. [tex]25+30x=y[/tex]
We can see that in this expression per month cost is changed with constant value, which means that cost for per month membership is $30 and joining charges are $25, therefore, 4th option is not a correct choice.
