If you purchased n T-shirts, the changes would be
n × -6.12 = -6.12n. This means a total debit of 6.12n for all the T-shirts you bought. Therefore,
6.12n = 30.6
n = 30.6/6.12 = 5

Customer 2: 5h + 3c = 11.75 → -2(5h + 3c = 11.75) → <u>-10h - 6c </u>= <u>-23.50</u>
2h = 3.50
<u> ÷2 </u> <u> ÷2 </u>
h = 1.75
