Answer:

the number of T-shirts bought was 5

Explanation:

After using a debit card, to purchase several t-shirts. Your account balance after buying the t-shirts changes by -$30.60. The negative sign means there was a total debit of $30.6 after your transactions. For each t-shirt you purchased , the changes in your account balance was -6.12. 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

So the number of T-shirts bought was 5
