Answer:
The price of each meal cost before tax is $ 6.367
Step-by-step explanation:
Given as :
The total price of three meals = $ 20.25
The sales tax included in the total price = 6 %
So, Let the cost of meal before sales tax = x
Or, x + 6 % of x = $ 20.25
or, x + 0.06 x = $ 20.25
Or, 1.06 x = $ 20.25
∴ x = 
I.e x = $ 19.10
Or, price of three meals before tax = $ 19.10
so, The price of each meal =
= $ 6.367
Hence The price of each meal cost before tax is $ 6.367 answer
-10 belongs to integers, rational numbers, and real numbers.
The correct answer when you plug in x and y values is -32 however that answer is not there . Perhaps they only wanted it before combining all like terms ? So again it really should be -32 , but if force yo pick
an answer from the choices I would pick -16
