Answer:
If only Jim purchased a cup of coffee, we will subtract its cost from the total;
9.50 - 1.00 = 8.50
Assuming that the two purchased nothing else for breakfast, and that the cost of an egg scramble was the same for both, let's call the price of the egg scramble x.
Since they both bought eggs, then 2x = 8.50
x = $4.25, the price for each egg scramble
The answer is -166, your welcome
Take half of the coefficient on the x term
Since 1 pound is $3.09, 4.5 pounds will be:

It says to round to nearest hundredth, so your answer is $13.91.
