Henry was buying meals for his family. He bought 3 meals that included a chicken, corn, and a drink and spent a total of $20.25.
riadik2000 [5.3K]

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 = \frac{20.25}{1.06}

I.e x = $ 19.10

Or, price of three meals before tax = $ 19.10

so, The price of each meal = \frac{19.10}{3} = $ 6.367

Hence The price of each meal cost before tax is $ 6.367   answer
