24 calculator 8 pens so 32 all together he had 16 dollars left because the fraction is 32/48 equals 2/3
apologiabiology
c=3 times p
c=3p
c=24
24=3p
divide both sides by 3
8=p

2/3 of money=c+p
2/3 of money=24+8
2/3 of money=32

how much he had left
all-2/3=1/3
so
2/3  of money =32
divide both sides by 2
1/3 of money=16

he had $16 left
