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

$14.20 was the price of her dinner before sales tax and tip.

Step-by-step explanation:

Zoe paid $18.60 in sales and tips for dinner.

Sales tax rate is 11% and she tipped 20%.

As we know Total payment of the dinner = Original price of dinner + tip + taxes

Let Zoe paid x rupees without taxes and tips.

So tips she paid = 11% of x = x(0.11)

And Taxes on the original price = 20% of x = x(.20)

Now total payment she made = x + 0.11x + 0.2x

18.60 = 1.31x

x = $14.20

Therefore, $14.20 was the price of her dinner before sales tax and tip.
