Since his wage is 8.75*63=551.25, we can add up the percentages to get 10+6.2+1.45+4+0.1=21.75%. To get 21.75%, we can move the decimal 2 to the left to get 0.2175. Multiply that by 551.25 to get around 119.9 dollars. If you'd like to calculate the individual taxes, you can apply a similar process to figure that out
M-7<6
add 7 to each side
M-7 +7 < 6+7
M < 13
this is true for all values of M less than 13
18 is the answer because... Woodwinds have 6, Percussion has 3, and Brass has 9! Hope that I helped! :)
X = (12/5,0)
y = (0,-4)
substitute 0 in for y & solve for x , to find the y-intercept substitute 0 in for x and then solve . ( I hope that makes sense)
