Maria scored 72, 97, and 82 on her first three math tests. She wants to have a mean score of 82 for the quarter. How many points

Rom4ik [11]

Answer:

She needs 77 on her last test to earn an 82 for the quarter.

Step-by-step explanation:

Maria scored 72, 97, and 82 on her first three math tests.

She wants to have a mean score of 82 for the quarter.

Let us assume that she must score x on her last test to earn an 82 for the quarter.

So the average score will be,

$=\dfrac{72+97+82+x}{4}$

But the average score is given as 82, so

$\Rightarrow \dfrac{72+97+82+x}{4}=82$

$\Rightarrow 72+97+82+x=82\times 4$

$\Rightarrow 72+97+82+x=328$

$\Rightarrow x=328-72-97-82$

$\Rightarrow x=77$

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.
