let Nathan's crayons be X
therefore jays Crohn's will be 15+x
And Monica's crayons will be 3×15+3×X=45+3x
according to question
they have 105 crayons altogether
therefore
x+15+x+45+3x=105
=>5x+60=105
=>5x=105-60
=>5x=50
=>x=50÷5
=>x=10
THEREFORE Nathan's crayons =10
jay's crayons =15+x=15+10=25
Monicas crayons =45+ 3×x=45+3×10=30+45=75
