What is the justification for step 3 in the solution process?
0.8a − 0.1a = a − 2.5
step 1: 0.7a = a − 2.5
step 2: -0.3a = -2.5
step 3: a = 8.3

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

if x decreases by 4 then y increases by 10

step-by-step explanation:

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
