Answer:
Part 1) The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.

Part 2) 
Step-by-step explanation:
Part 1)
Let
x-----> the number of pounds of regular coffee
we know that
The inequality that represent the situation is

Solve for x
Divide by 2 both sides


The maximum number of pounds of regular coffee that you can buy is 7.5 pounds.
The solution of the inequality is the interval ------> (-∞,7.5]
but the number of pounds cannot be a negative number
therefore
The solution is the interval -----> [0,7.5]
see the attached figure
Part 2) we have

I remember doing this question. The question went like:
<span>1.25x + 1.49 = 100
What error did Barbara make in writing the equation?
And the answer would be that Barbaras equation did not consider the number of ice tea drinks. Hence, </span>She put the correct price in the equation but she didn't put the (x) number of iced tea drinks. In other words,This is because she has added 1.25 X the number of water bottles sold to 1.49, the cost of one iced tea.
So, the correct equation would be:
1.25x +1.49y = 100
Would really appreciate if you would put me as Brainliest answer.
