1/2 S=T
1/3 S=scarf
so, S-1/2S-1/3 s=15
S(1-1/2-1/3)=15
S(6-3-2)/6=15
S(1)=90
goodness, she blew that 90 dollars away. 45 dollars on a T? 30 dollars on a Scarf?
Samantha went shopping and spent half her money on a T-shirt and a third of her money on a scarf. She returned with $15. How much money did she have to begin with?
My working out:
s = money to begin with
s - 1/2
s - 1/3 = 15

Just checking, the space between the s (money to begin with) and the fractions is multiplication? Thanks so much for your help.
