Respuesta :
a=25+2s, b=40+1.5s if they are equal...
25+2s=40+1.5s subtract 25 from both sides
2s=15+1.5s subtract 1.5s from both sides
.5s=15 divide both sides by .5
s=30
So if Louis sells 30 pair of shoes he will make the same either way.
25+2s=40+1.5s subtract 25 from both sides
2s=15+1.5s subtract 1.5s from both sides
.5s=15 divide both sides by .5
s=30
So if Louis sells 30 pair of shoes he will make the same either way.
