9. a school principal in modesto makes $2,755.58 weekly. what is their annual salary?
Answer
Explanation:
Step1: Know the number of weeks in a year
There are 52 weeks in a year.
Step2: Calculate the annual salary
Multiply the weekly salary by 52. The weekly salary is $2,755.58, so the annual - salary is $2755.58\times52$. $2755.58\times52=(2755 + 0.58)\times52=2755\times52+0.58\times52=(2700 + 55)\times52+29.16=(2700\times52+55\times52)+29.16=(140400+2860)+29.16 = 143260+29.16=143289.16$
Answer:
$143289.16$
