To join a local square dancing group, Jan has to pay a $100 sign-up fee plus $25 per month. Write an equation for the cost (y) b

klasskru [66]

Answer:

y = $100 + $25x

Step-by-step explanation:

y is the total cost

x is the number of months

The sign up fee is $100.

Each month would cost an additional $25 per month.

The total cost then would be the sign up fee plus the $25 for each month. Since we do not know the number of months, we will assign x.

So the equation would be:

y = $100 + $25x
