No
lets say a and b are positive numbers
that means -a and -b are negative
if you make the difference between these to it'd be
-a-(-b) which means -a+b, and if b>a then the difference is positive
Assuming they will all pay equaliy, including the tip,
100=orignal
100+20=120
120% of 62.50
ssimlify it
120/4=30
30% of 62.50=0.3*62.5=18.75
each person pays $18.75
The answer is 59. First you multiply 4 by 5 (20), then subtract 20 from 79 (59).
4(8x + 56) = 20
= 32x + 224 = 20
