The moral of the story is to not give up. The bird ,after discovering he couldn’t get the water after trying his hardest, still pushed through to pick up the stones to tip the pitcher to get the water.
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.
For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.
First, find out how much stan gets per week.
.25 x 7 =1.75
now how much they get together
1.75 + 1.20 = 2.95
and then the final step
23.60 / 2.95 = 8
it'll take 8 weeks for them to buy the model car set
A and C I think. I hope I helped a little bit
Given:
17%
To convert into decimal form:

Hence, the correct option is C.
