Answer:
r≈5.64
Step-by-step explanation:
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40

Answer:
The equation of the line is y -24 = -5(x + 6)
Step-by-step explanation:
To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-31 - 24)/(5 - -6)
m = (-31 - 24)/(5 + 6)
m = -55/11
m = -5
Now that we have the slope, we can use it and either point in point-slope form.
y - y1 = m(x - x1)
y - 24 = -5(x - -6)
y - 24 = -5(x + 6)
<span>There are 60 seconds in a minute.
To find out how many copies in a second, divide 36 by 60.
That is 0.6
Then you would calculate to see how much in 15 seconds,
0.6 times 15
9 copies in 15 seconds
then multiply 36 * 4 to see how many in minutes
144 copies in 4 minutes
153 copies in 4 minutes and 15 seconds.
Hope this helps :)
