Answer: The vendor sold 9.5 scarves.
Step-by-step explanation:
I know that 10 x 10 is 100. HOWEVER, this only tells how many gloves were sold. To get how many scarves were sold: you need to:
100 + 8x = 176 or 10 x 10 + 8x = 176
176 - 100 = 76 or 10 x 10 = 100 176 - 100 = 76
both problems 76 divided by 8 = 9.5
Thus, my answer would be 9.5 scarves were sold (or if you round, about 10 scarves were sold).
