Answer:
$1,149.75
Step-by-step explanation:
We can start this problem off by organizing the monthly and the annual expenses.
<u>Monthly:</u>
$725 - Condominium
$125 - Maintenance Work
<u>Annual:</u>
$468 - Insurance
$129 - Lost Interest
$3,000 - Utility Bills
Since we are solving for the average monthly expense, we should deal with the annual expenses first by dividing them all by 12 since there are 12 months.



Now, we simply add 299.75 to the monthly expenses to get our answer.


The average monthly expense is $1,149.75.
Answer:
a) rounded to the ones place and 2 significant figures.
b) rounded to tenths place and 1 significant figure.
Step-by-step explanation:
Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.
A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.
B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.
