The net change to her banking account balance is $83.22.

Step-by-step explanation:

Hi to answer this question we have to analyze the information given:

She spent $36.50 plus 8% tax.  ( to calculate the tax amount we have to multiply the cost by the percentage in decimal form)

36.50 x (8/100) =$2.92 (value of tax)

Adding to the original cost

36.50+2.92 = $39.42

Then, she spent $25 to refuel her car at the gas station.

39.42 +25 = $64.42

She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase

23.50 x (20/100) = 4.7 (amount of discount)

Subtracting to the purchase

23.50 -4.7= $18.8

Finally, adding to the total cost.

64.42 +18.8 = $83.22

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.

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
