Answer: $4.33
Step-by-step explanation: First add the cost of the items she bought together. 3.50 plus 1.75 equals 5.25. Then add that amount to the amount she had to pay for tax. 5.25 plus 0.42 equals 5.67. Finally, subtract the total from the 10 dollar bill she payed with. 10 minus 5.67 equals 4.33. She had $4.33 in change.
