Answer:
[tex]\$57.31[/tex]
Step-by-step explanation:
The total cost would simply be given by multiplying the price by 1.027
1) Divide the tax (2.7%) by 100 and then, add 1 unit
[tex]\frac{2.7}{100}=0.027+1\Rightarrow 1.027[/tex]
2) Multiply by the price ($55.80):
[tex]1.027*\$55.8\approx \$57.31[/tex]
