The table shows the price for different quantities of sponge brushes offered at a wholesale art supply store. Which is the BEST VALUE?
A) 20 brushes
B) 35 brushes
C) 50 brushes
D) 80 brushes
80 brushes (I have the same question on USA TESTPREP)
figure the cost per brush:
11.80/20 = 0.59
Now convert the others, and pick the lowest cost per brush.
I HATE MATH
To determine the best value among the given options, we need to compare the price per brush for each quantity. To do this, we divide the total cost by the quantity.
For option A (20 brushes):
Cost per brush = $11.80 / 20 = $0.59/brush
For option B (35 brushes):
Cost per brush = $17.15 / 35 ≈ $0.49/brush
For option C (50 brushes):
Cost per brush = $27.50 / 50 = $0.55/brush
For option D (80 brushes):
Cost per brush = $36.00 / 80 = $0.45/brush
Comparing the cost per brush, we can see that option D (80 brushes) has the lowest cost per brush at $0.45. Therefore, option D is the best value among the given options.
