Michelle and her roommate rent an apartment for $798 a month. Each of them pays half. Because there are about 4 weeks in a month, Michelle estimates her share of the rent is about $100 a week. Is that a good estimate? Yes

No, it is much high

Not, it is much low

yes

Step-by-step explanation:

half of $798 is $399. $100 a week × 4 = $400. 400 is very close to 399, so yes it would be a food estimate. Hope this helps! :)
