Question

A vendor sells gloves and scarves. Gloves cost S10 and scarves cost $8. If the vendor sold 20 total items for $176, how many scarves did the vendor sell?​

Answer 1

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).
