Question

Zoe paid \$18.60$18.60 in sales tax and tips for her dinner. The sales tax rate is 11\%11%, and she tipped 20\%20%. (The sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax.)

Answer 1

Answer: The price of billing is $221.40.

Step-by-step explanation:

Since we have given that

Amount Zoe has paid in sales tax = $18.60

Rate of sales tax = 11%

So, Let the original price be 'x'.

According to question, it becomes,

$\frac{11}{100}\times x=18.60\\\\x=\frac{18.60\times 100}{11}\\\\x=\ 169\ approx.$

Rate of tip = 20%

Amount of tip is given by

$\frac{20}{100}\times 169\\\\=\ 33.8$

Amount after tip is given by

$\ 169+\ 33.8\\\\=\ 202.8$

Hence, The price of billing is given by

$202.8+18.60\\\\=\ 221.4$
