Ginger wants to join a gym. She goes to the locax gym and is told that there is a one-time fee of $100 to join and then a monthly fee of $30. What algebraic expression represents the total cost of joining the gym? A) 130 B) 130m C) m - 30m D) 30m + 100 please help!! im don't know this​

i think its D) 30m+100

Step-by-step explanation:

Hi there!

it would be 30m+100

Expressions can’t have equal signs or just a number so we can cross out A and B...

m-30m means money-30 times money which doesn’t make sense.

30m+100 would be 30m+100 which is correct since the total would be 130$ and if m is 1, then this expression is correct,

Therefore, the expression would be 30m+100.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

because where the point where the 2 lines intersect is (3,-1) the x value is 3
