Can someone please help with this maths !!!!!
ioda

Answer:

C)  -3

Step-by-step explanation:

Rearrange your equation so that it is in slope-intercept form (y = mx + b).  The m in the equation is the gradient.

y = 7 - 3x

y = -3x + 7

The m-value is -3.  This means that the gradient is -3.

Farhan orders one plate of seafood fried rice at a restaurant which offers at 25% discount. the Marked price of the seafood frie
ANTONII [103]

Answer:

The total amount of money he has to pay for the dish is $8.3861.

Step-by-step explanation:

Here, the marked price of the seafood fried rice  = $9.50

Now, discount on the marked price  = 25%

Calculating 25% of $9.50 = \frac{25}{100}  \times 9.50 = 2.375

So, the discount offered = $2.375

Now, the Selling Price of dish = Marked Price - Discount

                                                    =  $9.50 - $2.375   = $7.125

Now, here the service charge applied here  = 10%

Calculating 10% of $7.125 = \frac{10}{100}  \times 7.125 = 0.7125

So, the service charge applied  = $0.7125

So, the new Selling Price of dish = Selling Price + Service Charge

                                                    =  $7.125 + $0.7125   = $7.8375

Again, here the GST applied here  = 7%

Calculating 7% of $7.8375 = \frac{7}{100}  \times 7.8375 = 0.5486

So, the GST applied  = $0.5486

So, the new Selling Price of dish = Selling Price + GST

                                                    =  $7.8375 + $0.5486   = $8.3861

Hence, the total amount of money he has to pay for the dish is $8.3861.
