I would start with writing an equation. You could make a table but that might take a long time.
x= Layla
x+1= Joe
x+x+1=105
2x+1=105
sub 1 from each side
2x=104
divide both sides by 2
x=52
So, Layla would make $52 in profit
36000 over 1 to get the fraction of 36000
Average rate of change of section A = (f(1) - f(0))/ (1 - 0) = (5(1) - 5(0))/(1 - 0) = (5 - 0)/1 = 5
Average rate of change of section B = (f(3) - f(2))/(3 - 2) = (5(3) - 5(2))/(3 - 2) = (15 - 10)/1 = 5
Average rate of change of section B is equal to that of section A.
What’s the whole question???!
