Okay, so since her annual salary is <span>$52,750 (the amount she gets a year, all twelve months combined) you're trying to find how much she gets monthly. That would mean we would have to divide her annual salary by 12 to find her monthly salary.
</span>$52,750 ÷ 12 = 4,395.8333333333333
<span>
And since that's a (bothersome) repeating decimal, we're going to have to round it. Once rounded, you would get $</span>4,395.83. That is her monthly salary.
Answer:
12.5%
Step-by-step explanation:
The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??
The increase is 900 - 800 = 100
To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:
So the increase is 12.5% and thus the general sales tax is 12.5%
Answer:
Both of the equations are right because if you take s=4p, then reverse it, p=1/4 of s because 4 of p is equal to s so s/4 = p
Answer:
50,000 ≤ 23,210 + 5x
x = Average number of words per week
Step-by-step explanation:
Start off with 50,000 because that's how many words the paper needs to have.
Use "≤" because Trevor needs to write at least 50,000 words. (He can write more).
Trevor already wrote 23,210 words plus x words per week for 5 weeks.
(Solving for x will help you find the average number of words Trevor must write per week for 5 weeks).
