<h2>We know:</h2>
You currently make $13.50 an hour. You've earned a 15% pay raise. You want to find out your previous rate of pay per hour.
<h2>Steps:</h2>
1.) Convert 15% to a decimal, which equals 0.15
2.) Multiply your current earnings with the percentage in decimal form (0.15)
$13.50 (current pay per hour) x 0.15 (percentage in decimal form) = $2.025 (difference between your previous wage and your current wage)
3.) Subtract the difference of your previous wage and current wage with your current earnings
$13.50 (current pay per hour) - $2.025 (difference between previous and current wage) = $11.475 (previous pay per hour)
4.) Since this is talking about wage, rounding is not applicable. In other cases, your number would be rounded off to $11.48, however you can't add what you don't have, so you would have to round down.
<h2>
You were previously making $11.47 an hour.</h2>
Answer:
Step-by-step explanation:
Hi there,
To get started, recall the logarithm rules. For this question, we can use the log rule specifically when subtracting two log functions that have the same base:
![log_b\alpha -log_b\beta =log_b[\frac{\alpha }{\beta } ]](https://tex.z-dn.net/?f=log_b%5Calpha%20-log_b%5Cbeta%20%3Dlog_b%5B%5Cfrac%7B%5Calpha%20%7D%7B%5Cbeta%20%7D%20%5D)
In this prompt, our base is 4, so b in the above formula. Using this formula, we can find the missing <u><em>argument</em></u> (the number inside of the log, what we are asked to solve for):
![log_49-log_411=log_4[\frac{9}{11} ]\\](https://tex.z-dn.net/?f=log_49-log_411%3Dlog_4%5B%5Cfrac%7B9%7D%7B11%7D%20%5D%5C%5C)
hence the missing argument is 9/11
At this point, there is no easier say to simplify, unless you wish to approximate 9/11 as 0.818. If you wish to solve for the exponent, you will have to use common log or natural log to do so.
