i think the second question (the choose the Function) means choose the function that has changed the most.
the first choose function one, i dont know but... according to wikipedia, "an initial value problem is an ordinary differential equation together with an initial condition which specifies the value of the unknown function at a given point in the domain. Modeling a system in physics or other sciences frequently amounts to solving an initial value problem." hope this helps
$36 I think $0.89 rounds up to $1.00 $0.75 rounds up to $1.00 $1.60 rounds up to $2.00 then multiply each by 9 for the 9 children 9 9 18 then add together 9+9+18=36
