You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

Answer:
polygons
Step-by-step explanation:
this is a hexagon so the sum of interior angles is 720. so add all of those angles and expressions and set it equal to 720. collect like terms and solve for x
once you have x, evaluate and get the exact angle measurements.
Answer:
25% is called a quarter of 900
Step-by-step explanation:
![{ \tt{25\% = \frac{25}{100} = \frac{1}{4} }} \\](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B25%5C%25%20%3D%20%20%5Cfrac%7B25%7D%7B100%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%20%7D%7D%20%5C%5C%20)
Kevin painted
of the wall.
Solution:
Fraction of the wall painted by Elena = ![\frac{5}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7D)
Fraction of the wall painted by Matthew = ![\frac{3}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B9%7D)
Fraction of the wall painted by Kevin = ?
Full wall can be taken as 1.
<u>To find the wall painted by Kevin:</u>
Rest of the wall = Full wall – painted by Elena – Painted by Matthew
![$=1-\frac{5}{9}-\frac{3}{9}](https://tex.z-dn.net/?f=%24%3D1-%5Cfrac%7B5%7D%7B9%7D-%5Cfrac%7B3%7D%7B9%7D)
![$=\frac{1}{1} -\frac{5}{9}-\frac{3}{9}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B1%7D%7B1%7D%20-%5Cfrac%7B5%7D%7B9%7D-%5Cfrac%7B3%7D%7B9%7D)
To make the denominator same, multiply the numerator and denominator of the first term by 9.
![$=\frac{9}{9} -\frac{5}{9}-\frac{3}{9}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B9%7D%7B9%7D%20-%5Cfrac%7B5%7D%7B9%7D-%5Cfrac%7B3%7D%7B9%7D)
![$=\frac{9-5-3}{9}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B9-5-3%7D%7B9%7D)
![$=\frac{1}{9}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B1%7D%7B9%7D)
Rest of the wall = ![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
Hence the kevin painted
of the wall.
