y= mx+b
(16, -7) = (x,y)
2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y
2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2
Insert the values into y = mx + b
solve for m and then solve for b
1.3, 1 1/3, 1.34
The decimal version of 1 1/3 is 1.333 (so on)
so 1.3 is less than 1.333 and 1.333 is less than 1.34
1.3<1.333<1.34
5(n+6)=48
5n+30=48
5n=18
n=18/5
The discount is 50-14 = $36
% discount = (36/50)*100 = 72%
