21. The answer is 453. I put it in the calculator and got 452.5, so I rounded to 453. If it's 5 or more round up, 4 or less round down.
22. 14.1 I did the same thing it came out as 14.06, but the 6 made me round to 1.
23. $4.1 I think you get the concept now.

for every weekend that mia does her household chores her mother gives her $9.for how many weekends does mia have to do her chore
allsm [11]
So, we'll say Mia gets $4.50 a day, since a standard weekend is two days, therefore adding up to $9 a weekend. So if Mia were to do her chores for 4 weekends, she'd have a total of $36 but not $40. So if she were to work an extra weekend, so 5 weekends, she'd have a total of $45. So you can say 5 weekends in order to earn more than $40.
