mommy


I normally I stand her walker next to her http://reviews.argos.co.uk/1493-en_gb/3482625/reviews.htm as it lights up she gets half way but no further an manages to shift around the room on her back, she rolls front to back and sits up but cant yet manage to get her the other the way I spend most my days on the floor to no avail any ideas?


Answer
When you're on the floor playing with her, get her really excited about a toy that you hold just out of reach. Move it in the direction you want her to roll and when she's all the way on one side drag it across the floor slowly so she has to reach above her head and roll to try to get it. Don't be discouraged if she doesn't get it fright away, and don't push he too much either.

It sounds like she's doing great, just isn't interested in rolling onto her tummy. Trust me, its easier thatway - ever since Ella figured it out changing her diaper has been crazy difficult - as soon as the old one is off she flips over and tries crawling away!! Trying to hold down a squiggly baby AND get a new diaper on is quite a challenge

I need help with my math review. How do I correctly solve this problem using Linear Programming?

Here is the question:
A toy manufacturer is introducing two new dolls, My First Baby and My Real Baby. IN one hour, the company can produce 8 First Babies or 20 Real Babies. Because of demand, the company produces at least twice as many First Babies as Real Babies. The company spends no more than 48 hours per week making these two dolls. The profit on each First Baby is $3.00, and the profit on each Real Baby is $7.50. Find the number and type of dolls that should be produced to maximize profit.

I used F for fthe number of First Babies and R for the number of Real Babies. All I am sure of is that F is greater than or equal to zero, R is greater than or equal to zero and that F is greater than or equal to 2R. I am unsure of the other equations needed to be graphed, since I keep getting the wrong answers. The correct answer is 320 First Babies and 160 Real Babies. How do you get that as a maximum value?



Answer
This is what i make of it :

F >= 0
R >= 0
F >= 2R
F/8 + R/20 <= 48
max P(F,R) = 3F + 7.5R

"draw the lines , the theory says that your max is on an corner." or use a tableau method.
