#21-3: in 1985, a gallon of mil costs $2.26. in 2005 the price increased to $2.45. find the percent of increase for the cost of a gallon of milk. find the amount of increase and divide by the original amount. round to the nearest tenth.

8.4

Step-by-step explanation:

1985 milk price: $2.26

2005 milk price: $2.45

2.45-2.26=0.19/2.26= 0.0840708 x 100 = 8.40707965 round to 8.4

You will minus the 2005 price by the 1985 price, and then divide by 1985 price. After that step, you will multiply by 100 and round to the nearest tenth.

here’s the answer.

Step-by-step explanation:

The coordinates of a point satisfies the equation of a line if the point lies on the line

If a single point satisfies the equations of two lines, the point is on both lines, so the lines will intersect at that point.

This means that each point where the two lines touch is a solution to the system of equations

This means that if you substitute the x and y values of the point for x and y in the equations, both equations will be true.

hope this helps!..
