A basic manicure starts at $35 while a pedicure starts at $40. A certain salon offers 20% off if you get both. Suppose Karen chooses to do both and would also like to add nail art on each of her fingers, which costs $3 per nail. How much would she pay in all?
The cost for both manicure and pedicure is $35+$40=$

<output>75</output>
75.
The discount is $75*0.2=$
<gadget id="calculator">75*0.2</gadget>
<output>15</output>
15.
So, Karen would only pay $75-$15=$

<output>60</output>
60 for both services.
The cost of the nail art for 10 fingers is $3*$10=$

Therefore, Karen would pay a total of $60+$30=$
