Answer:
Step-by-step explanation:
100 + 100 + 6x + 6 + 12x - 8 = 360 Equation. Collect like terms.
198 + 18x = 360 Subtract 198 from both sides
18x = 360 - 198
18x = 162 Divide by 18
x = 162/18
x = 9
The slope is -2/3.

Answer is 34.96$ for the final cost.
Answer:
For each part, find how many numbers have the stated characteristic, then divide by 21.
e.g. multiples of 5:
these would be 10, 15, 20, 25, and 30
so prob (a multiple of 5 ) = 5/21
Do the others the same way
