166 - 98 = 68 are square
68/7 = 9.7....he would actually need 10 bins

Answer:

about 10 bins

Step-by-step explanation:


First, we need to find out how many doorknobs are square:

166 - 98 = 68

Then, we need to divide the number of square doorknobs, 68, by the number of square doorknobs in each bin, 7: 68 ÷ 7

68 is closer to 70. So,

68 ÷ 7 is about 70 ÷ 7.

So, 68 ÷ 7 is about 10.
