2 answers:
Because this is a linear problem, I'd use the slope-intercept formula:
where
m = slope (rise/run)
y = dependent value
x = independent value
b = constant value
Because the plumber charges $17 upon arrival, it is our constant. The $36 is our slope (<em>per</em><em> </em><em>hou</em><em>r, per minute, per etc.</em> is generally a give away). Additionally because the total cost of the plumber's visit depends on how long s/he stays at a client's home, the $89 is our y value. Therefore the equation should look like this:
Solve for x by subtracting 17 from both sides of the equation then dividing by 36.
The plumber spent two hours at his/her client's home.

Answer:
15 bags
Step-by-step explanation:
She can fill 5 bags per each pound (because there are 5 per pound)
Since there are 3 pounds, and , again, each pound can fill 5 bags, she will need 15 bags.
Another way too look at it is to ask how many 1/5ths are in 3 pounds. To find this answer mathematically:
3 ÷ 1/5 = 15 because when we divide by a fraction, we need to flip it and then multiply (so 3 ÷ 1/5 is actually 3×5)
