Stevie paid $45.75 for her dinner. She left a 20% tip and paid 7% sales tax. What is her total bill including tax and tip?

$12.35
$33.25
$54.90
$58.10

First calculate the amount of the tip by multiplying Stevie's meal cost by 20%: $45.75 * .2 = $<<45.75*.2=9.15>>9.15

Then multiply Stevie's meal cost by 7% to find the amount of the sales tax: $45.75 * .07 = $<<45.75*.07=3.2025>>3.20
Then add the cost of the meal, the tip, and the tax to find Stevie's total bill: $45.75 + $9.15 + $3.20 = $<<45.75+9.15+3.2=58.10>>58.10. Answer: \boxed{58.10}.
