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

2.02b + 4.30 = 2.00b + 6.30
bonufazy [111]

Answer: b = 100

Step-by-step explanation:

simplifying

2.02b + 4.30 = 2.00b + 6.30

reorder the terms:

4.30 + 2.02b = 2.00b + 6.30

reorder the terms:

4.30 + 2.02b = 6.30 + 2.00b

solving

4.30 + 2.02b = 6.30 + 2.00b

solving for variable 'b'.

move all terms containing b to the left, all other terms to the right.

add '-2.00b' to each side of the equation.

4.30 + 2.02b + -2.00b = 6.30 + 2.00b + -2.00b

combine like terms: 2.02b + -2.00b = 0.02b

4.30 + 0.02b = 6.30 + 2.00b + -2.00b

combine like terms: 2.00b + -2.00b = 0.00

4.30 + 0.02b = 6.30 + 0.00

4.30 + 0.02b = 6.30

add '-4.30' to each side of the equation.

4.30 + -4.30 + 0.02b = 6.30 + -4.30

combine like terms: 4.30 + -4.30 = 0.00

0.00 + 0.02b = 6.30 + -4.30

0.02b = 6.30 + -4.30

combine like terms: 6.30 + -4.30 = 2

0.02b = 2

divide each side by '0.02'.

getting:  b = 100

A meteorologist reports that there is a 30% chance the temperature will fall below freezing tomorrow. On any given day, the bus
sladkih [1.3K]
<h3>Answer:  18%</h3>

===========================================================

Explanation:

Convert each percentage to decimal form

  • 30% converts to 0.30
  • 60% converts to 0.60

Then multiply the decimal values

0.30*0.60 = 0.18

That converts to 18%

So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.
