So according to the problem, the tax should be calculated using the bill.
So 5.5% equals to 0.055.
Then multiply 0.055 and 74.98.
Thus resulting in 4.1239 and when rounded, the answer should be 4.12, C
-5x - 7 < 28.....add 7 to both sides
-5x < 35....divide both sides by -5, change the inequality sign (u change the inequality sign when dividing/multiplying by a negative number)
x > -7
-5/6=(8,4)(x,y)
-5/6=y-4/x-8
6y-24=-5x+40
6y=-5x/6+64/6
Y=-5x/6+64/6
Set up proportion 170/180=x/1 than cross multiply 170x=180 divide both sides by 170 answer 0.944 so 94% remains
