If Julie bought 8 Tshirts, she would be short $28. If she bought 4 Tshirts and 3 baseball hats, she would have $17 left. If each hat cost $5, how much money did she have in the beginning

if she has x dollars,
8t = x+28
4t+3h = x17
h=5
so,
4t+15 = x17
x = 4t+32
8t = 4t+32+28
4t = 60
t = 15
x = 60+32 = 92
check:
8*15 = 120 = 92+28
4*15+3*5 = 75 = 9217
