Answer:

1) The discount is $4.05

The sale price is $18.45

2) The discount is $10

The sale price is $30

3) The discount is $2.6

The sale price is $23.4

Step-by-step explanation:

1) What is the discount and sale price for a haircut that originally cost $22.50 with an 18% discount.

Actual Price= $22.50

Discount = 18%

Finding discount:

$18\%\:of\:22.50\\=\frac{18}{100}\times 22.50\\=4.05$

So, the discount is $4.05

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=22.50-4.05\\Sale\:Price=18.45$

The sale price is $18.45

2) What is the discount and sale price for a sweatshirt that originally priced $40.00 with an 25% discount.

Actual Price= $40.00

Discount = 25%

Finding discount:

$25\%\:of\:40.00\\=\frac{25}{100}\times 40.00\\=10$

So, the discount is $10

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=40.00-10\\Sale\:Price=30$

The sale price is $30

2) What is the discount and sale price for a large pizza that originally cost $26.00 with an 10% discount.

Actual Price= $26.00

Discount = 10%

Finding discount:

$10\%\:of\:26.00\\=\frac{10}{100}\times 26.00\\=2.6$

So, the discount is $2.6

Finding Sale Price

The sale price can be found by: $Sale\;Price=Actual\:Price-Discount$

Putting values and finding sale price:

$Sale\:Price=26.00-2.6\\Sale\:Price=23.4$

The sale price is $23.4

Jafar will get $12400 more if his salary is increased by 31%. Jafar's salary is 20% less of his colleague Ali's salary. What is

Iteru [2.4K]

Answer:

Ali's salary is $50000.

Step-by-step explanation:

Let Jafar's salary be x.

(31/100)*x = 12400

x = (12400*100)/31

x = 400*100

x = $40000

Let Ali's salary be y.

y-[(20/100)*y] = 40000

y-(y/5) = 40000

(5y-y)/5 = 40000

4y = 200000

y = $50000

Y=-2x+8 equation 1

y=x-1 equation 2

x-1=-2x+8 substi y of second equation into y of first equation.

3x=9

x=3

solve for y by putting the x value into either equation

y=x-1

y=3-1

y=2

Mr.Afzal bought an article for Rs4400 for 3years at 8 percent what was the interest charge?

zimovet [89]

$\large\underline{\underline{\red{\rm\blue{\longmapsto} Step-by-step\: Explanation:-}}}$

Here , the given data is :

Principal = Rs 4400 . ( P )
Time = 3 years . ( T )
Rate of Internet = 8% . ( R )

We can calculate Simple Interest using ,

$\boxed{\purple{\bf Simple\: Interest=\dfrac{P\times\:R\:\times\:T}{100}}}$

On substituting the respective values ,

⇒ SI = P × R × T / 100.

⇒ SI = Rs 4400 × 8 × 3 / 100 .

⇒ SI = Rs 44 × 8 × 3 .

⇒ SI = Rs 1,056 .

Hence the required Interest is Rs 1,056.
