She owes in total 40$ in total but seprate
Cost of each shirt bought by Brain = 14.50
Then
Cost of 2 shirts bought by Brain = 2 * 14.50
= 29
Cost of a pair of shoes = 29.99
Total amount spent by Brain before tax = 29 + 29.99
= 58.99
Percentage of sales tax that needs to be paid = 6%

= 3.54
So
the total amount spent by Brain including tax = 58.99 + 3.54
= 62.53
I hope this is the answer you were looking for.
Steps to simplify:
(2x + 3)(x - 7)
~Use FOIL to multiply
(2x * x) + (2 * -7) + (3 * x) + (3 * -7)
~Simplify
=2x² - 14x + 3x - 21
~Combine Like Terms
2x² + (-14x + 3x) - 21
~Simplify
2x² - 11x - 21 (Option 2)
Best of Luck!
