A bakery is offering a promotion where a customer can buy a dozen cookies for $9.50. Normally, the cookies cost $1.25 each. By how
much is the cost of the cookies discounted? Round to the nearest
whole percent, if necessary.

The cookies are discounted by 37%.

Step-by-step explanation:

Given that:

Promotional price of cookies = $9.50

Normal price = $1.25 per cookies

Cost of dozen = 1.25*12 = $15

Discount amount = 15 - 9.50 = $5.50

Percent discount =

Percent discount =

Percent discount = 36.6%

Rounding off to nearest whole percent

Percent discount = 37%

Hence,

The cookies are discounted by 37%.

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
