when two is added to two the result is 4 !!
2+2=4 !!!
(a) 2.49 * 6 = 14.94 <== what they spent on goodie bags
(b) 150 for 8 hrs = 150/8 = 18.75 per hr
(c) 182.53 - (150 + 14.94) = 182.53 - 164.94 = 17.59...they spent 17.59 more
10/2=5 64/2=32 5/32 is simplest form
The common ratio of a geometric sequence is the ratio of any term to the one before it. Here, you can find it by
... 6/-2 = -3
or, if you prefer the minus sign in the numerator, ...
... -18/6 = -3
or the ratio of any other sequential terms.
The common ratio is -3.
To solve the problem you have to isolate or separate x from everything else. That means adding 3 to both sides to start.
