At the beginning of the first day, Ann has $25$ dollars. By the end of the first day, Ann has 2/3 of the money that she had at the beginning of the first day. By the end of the second day, Ann has4/7 of the money that she had at the end of the first day. How much money does Ann have at the end of the second day? Express your answer (in dollars) as a fraction.

  $200/21

Step-by-step explanation:

1st day start:  $25

1st day end: $25 * 2/3 = 50/3

2nd day end: 50/3 * 4/7 = 200/21

$200/21 or $9.52

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
