you earn $8.50 per hour. then you receive to $9.35 per hour. find the percent increase. then find your pay per hour if you receive the same percent increase two more times.
The percent increase is calculated by the following formula: \( \dfrac{ \bf new~amount - old ~amount}{\bf old ~amount} \times 100\% \)
im learning this in school and its pretty fun and easy (: just follow the formula mathstudent55 gave you its really simple! need more help?
so is 9.35 - 8.50 8.50 @mathstudent55
first whats 9.35 - 8.50
is 0.85
ok now divide 0.85 by 8.50
\(\dfrac{9.35 - 8.50}{8.50} \times 100\% = \)
what did you get?
0.1
\( \dfrac{0.85}{8.50} \times 100 \% \) \( = 0.1 \times 100\%\) \( = 10\% \) The percent increase is 10%.
0.1 times 100% =10% and its increase (:
thank you so much

Now for the second part. If you receive the same pay raise two more times, then you will end up with the following. Since now $9.35 is your salary, and the full salary is 100%, a ten pecent increase would make it 110% of what you are receiving now. 110% * $9.35 =1.1 * $9.35 = $10.285 After the first of the two 10% percent increases, the new salary is $10.285. $10.285 is now 100% of your salary. A second 10% increase means the new salary becomes 110% of the current salary, so the new salary after the second 10% increase would be: 110% * $10.285 = 1.1 * $10.285 =$11.3135 The new salary is $11.31 per hour.
thank you so much
