If the cost of a dress is $75.00 and
11Alexandr11 [23.1K]

Answer:

80%

Step-by-step explanation:

Original price =$75.00

Sale price =$60.00

The percentage discount can be calculated by dividing the sale price by the original price multiplied by 100%.

So % discount = $60.00/$75.00 x 100%

0.8 x 100%

80%

Janelle got the dress on a discount of 80%.

This is so because she got the dress for a price less than the original price

What is the equation of the line that passes through the point (4,7) and has a slope of o?
Svetlanka [38]

Answer:

The equation of the line that passes through the point (4,7) and has a slope of 0 will be:

  • y=7

Step-by-step explanation:

As we know the equation of a line in a slope-intercept form of an equation is

y = mx + b

Here,

  • m is the slop
  • b is the y-intercept

so

substituting the point (4,7) and slope m=0

y = mx + b

7=0(4)+b

7=0+b

b=7

Therefore, the equation of the line that passes through the point (4,7) and has a slope of 0 will be:

y = mx + b

y=0x+7

y=7
