Kayla has a T shirt store. she sold three times as many white T shirts as blue T shirts, she sold a total of 48 T shirts. how many white T shirts did kaylal sell

WT is white T shirts

BT is blue T shirts, and WT=3BT

WT+BT=48

3BT+BT=48

4BT=48

BT=12 so WT =3×12=36

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
