Since she had $35.48 on her card.
Amount spent in buying coffee = $70 - $35.48 = $34.52
Cost of coffee = $8.63 per pound
No of pounds = Amount spent / cost per pound

The answer is 1/2lbs, here's how.
3/4x2/3=6/12 reduced to 1/2lbs.
First you need to multiply 36 *$30.22=$1087.92
This gives you the total amount paid
Then subtract 1087.92-900=187.92
This gives you the amount of money you paid in finance charges.
40% helping customers + 13% doing paper work = 53% of his time.
This means 100% - 53% = 47% of his time he is doing other tasks.
