Zoe paid 18.60 in sale taxes ans tip her dinner. The sale tax rate is 11%and she tipped 20% what was the price of zoes dinner before sales tax and tip

Answer: the price of Zoe's dinner before sales tax and tip was $60

Step-by-step explanation:

Let x represent the original price of the dinner. If the sales tax rate of the dinner is 11%, it means that the amount of tax that Zoe paid would be

11/100 * x = 0.11 * x = 0.11x

She also gave a tip of 20%. Assuming she gave the tip on the original price of the dinner, then the amount of tip that she gave would be

20/100 * x = 0.2 * x = $0.2x

If Zoe paid 18.60 in sale taxes and tip on her dinner, it means that

0.2x + 0.11x = 18.60

0.31x = 18.6

x = 18.6/0.31

x = $60
