The total charge to her account balance is $83.22

Step-by-step explanation:

We are told that she initially spends $36.50 at the clothing store plus 8% tax.

8% of $36.50 is:

8 / 100 * 36.50 = $2.92

Her total spending at the clothes store is therefore

$36.50 + $2.92 = $39.42

She then spend $25 to refuel her car.

She then bought groceries worth $23.50 and handed over a coupon for a 20% discount on her purchase.

20% discount means 20% of her cost was deducted from what she was supposed to pay and she only paid 80% of the amount she was supposed to pay.

80% of $23.50 is:

80 / 100 * 23.50 = $18.80

Therefore, her total cost (change in her account balance) is:

$39.42 + $25 + $18.80 = $83.22

The total charge to her account balance is $83.22.
