The best way to solve this is to put it into a proportion:
So you cross multiply to get:
(the 21 is from
•84)
Then multiply by
And you get $28, so the reduced price would be $28.

x≤8
Answer: x≤8 or (-∞,8]
Answer:
3n
Step-by-step explanation:
We can see that the 3 gets distributed into the parentheses since there is a +21 on the right (3×7=21) so we also have to distribute the 3 to the n
100/99 is one, there are infinite answers though
