Answer:

I believe your answer is C 94.79

If this answer is wrong please let me know my apologies

Step-by-step explanation:

If my math is correct

44.50+44.50=89

Now, find the tax value by multiplying tax rate by the before tax price:

tax = 85 × 0.065

tax = 5.53 (tax value rounded to 2 decimals)

Add tax to the before tax price to get the final price:

The final price including tax = 85 + 5.53 = 90.53

90.53 plus the shipping 3.89=94.79

But going off the average number of items, you have 8 green, 5 yellow, and 8 blue. So you can add them together for 21. From here, you divide 21 by 3 to get your average, 7.
