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.

Enrique and Yolanda collected 500 pieces of candy on Halloween. They gave half of their candy to charity. Yolanda took 180 piece

777dan777 [17]

The answer would be C. (He counted Yolanda's candy as his own).

This is found by multiplying 500 (starting number of candy) and .64 (percentage divided by a hundred). Thjs would guve you 320, which you would then subtract from the starting number of candy (500) to get 180. 180 is Yolanda's number of candy, which gives you the answer.

Use the graph to determine the number of solutions the system has. x=4 y=x+3

Lyrx [107]

Answer:

Final answer is x=4, y=7.

Step-by-step explanation:

Questions says to use the graph to determine the number of solutions the system has. where system of equations are x=4 and y=x+3

any equation of the form x=k is a vertical line crossing x-axis at k.

So x=4 is a vertical line crossing x-axis at 4.

y=x+3 has slope m=1 and y-intercept b=3

So it passes through point (0,3) and for slope m=1, rise 1 up then 1 right to get new point.

Then final graph is given as shown in the picture.

We can see that both lines intersect at point (4,7).

Hence final answer is x=4, y=7.
