Let Joe initially have J dollars, and Mary have M dollars. Let the price of the T-shirt be T dollars.
i) "<span>Before they buy it, Mary has 2$ more than Joe":
means M=J+2
ii)
"</span>To buy the T-shirt, Joe spends 1 $ less than \frac{2}{5} of his money<span>"
so </span>
<span>
iii)
</span><span>"Mary spends \frac{1}{3} of her money"
</span>
means
equalize equations ii) and iii):
(they are both equal to T)
substitute M=J+2 from equation i:
6J-15=5J+10
J=25
so M=25+2=27 (dollars)
Together Mary and Joe had 27+25=52 (dollars)
Answer: 52 $
