Answer
A
Vera has been billed correctly.
B
Vera has not been charged enough for her purchase.
C
Vera has been over charged by $1.13 for her purchase.
D
Vera has been over charged by $3.50 for her purchase.
Explanation
The prints cost 3 × $0.89 + 12 × $0.15 + 1 × $2.99 = $7.46. Adding the $8.69 album gives a purchase total of $16.15, so standard shipping is free because the purchase is up to $20. The 7% tax is about $1.13, making the correct total about $17.28. Vera was billed $20.78, which is $3.50 too much, so she was overcharged by $3.50.
