Question

Devi orders one bowl of ramen at a Japanese
restaurant which offers an 18% discount. There is
a service charge of 10% and GST is at 7%. Given
that she pays a total of $10.13, find the marked
price of the ramen​

Answer 1

Answer:

Let x equal the marked price of ramen.

The 18% discount is equal to x+-+0.18x, or 0.82x

The service charge, when applied to the discounted ramen price, is 0.1%280.82x%29

The GST, when applied to the discounted ramen price, is 0.07%280.82x%29

Since she paid all 3 of these, and it totaled to 10.13, you can add them together to get this equation:

0.82x+%2B+0.1%280.82x%29+%2B+0.07%280.82x%29+=+10.13

Combine the terms to get:

+0.9594x+=+10.13

Divide by 0.9594 to get: x+=+10.55

So, the original price of the ramen was 10.55.

Answer 2

Answer:

The market price of one bowl of ramen is $ 12.14  

Step-by-step explanation:

Given as :

The total amount paid for bowl of ramen = $10.13

The discount on ramen = 18 %

The service charge applied = 10 %

The GST applied = 7%

Let The market price of bowl of ramen = $x

So, According to question

The price of ramen after 18% discount = x - 18% of x

                                                                = 82% of x

Now,

82% of x  + 10 % + 7 % = $10.13

Or, 82 % of x = 10.13 - 0.1 - 0.07

Or,  82 % of x = 9.96

Or,   x = = $ 12.14

Hence The market price of one bowl of ramen is $ 12.14
