Step-by-step explanation:
For the set of of each equation, it will be:
y = mx + b
x represents the number of weeks a child saved so we must multiply that by however much they saved during those weeks - hence, why there is an m there
y represents the total amount of money saved
b represents how much money they started off with (which is why we add b instead of multipling)
For Jeanne:
y = mx + b
She started with $1
y = mx + 1
She saved $5 every 3 weeks (this is multiplication)
y = 5(3) + 1
I have to go back to work now, but if you want me to show you the rest of the equations I will be more than happy to do so (I'll be available in 2 hours)
I hope my explanation helps
