Regular price = 2.19
THen you get a discount of 10%.
On top of that amount, you pay sales tax of 7%.
So,
10% means 10/100 = 0.1
So, we subtract this amount:
2.19 - (0.1)(2.19) = 1.971
Now, we need to add 7% as sales tax,
7/100 = 0.07
Thus,
1.971 + (0.07)(1.971) = 2.109
Rounding to 2 decimal place, 2.11
Correct answer is $2.11, Answer choice C
