Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
so to find that you can use y=mx+b, or you can use point slope form and that would be y-y1+m(x-x1)
remember m= slope b= y- intercept
Karen bought 8.5 pounds of flour. She uses only 2.5 pounds of flour to make the bread.
So, the amount of flour left after baking the bread = (8.5 - 2.5) pounds
= 6 pounds
So 6 pounds of flour is left. She breaks this 6 pounds of flour into several bags and each bag contains 2/5 pound of flour.
Now to calculate the 2/5 th pound of flour in decimal, we get = 0.4 pounds
So each of the bags contain 0.4 pounds of flour. Now we have to calculate the number of bags in which the flour have been kept.
So,
Number of bags required = 6/0.4
= 15
So 15 small storage bags are required by Karen to keep the remaining flour.
First, divide $8 with 20
8/20 = 0.4
Each copy costs 40 cents.
Multiply the cost for each copy with the amount of copies to be made
0.40 x 85 = 34
$34 is the cost to make 85 copies
