To join a dance class, there is an enrollment fee of $50 plus a monthly fee of $65. how many months of dance, d, can audra take if she has $850 to spend on dance?

Hi Candisjhnsn,

To get the answer we need to add, subtract, and divide. So, for the first month we pay $115 cause $65 + $50 = $115. So, $850 - $115 = $735. Now, $735/$65 = 11.3076923077 but, you can't have .3076923077 of a class so, she will only have enough for 11 classes.

Hope This Helps!

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
