J.M.'s Proportion Problem
1) Three posters cost $ 9.60. At that rate, how many posters can you buy for $ 48?
Let x be how many posters can be bought with $48
Steps, Word Ratio, Ratio Table
Poster| $
3 | 9.60 9.60x = 3
x | 48 9.60x = 144
9.60 9.60
x = 15
I can buy 15 posters with $48.
2) You estimate that you can do 12 math problems in 45 minutes. How long should it take you to do 20 math problems?
Let x be the minutes it should take me to do 20 math problems
Steps Word Ratio, Ratio Table
Minutes | Math Problems
45 | 12 12x = 45
x | 20 12x = 900
12 12
x = 75
It should take me 75 minutes for me to do 20 math problems
Which cost more per issue, an 18 - issue subscription for $40. 50 or a 12 - issue subscription for $33.60?
3) Let x be
Steps, Word Ratio, Ratio Table
Subscription | $
18 | 40. 50
12 | 33.60

Jm's Rate Problem
Group Problem :
1) There was a farmer named J.M. he left his farm from 1 pm to 6 pm. When he came back the chickens he was taking care of laid 5 chicken eggs. How many chicken eggs did the chicken laid per hour?
My own problem :
1) If there are 15 cats per 10 dogs, how many cats are there if there is only 5 dogs?
2) If David drove 100 miles/13 hours, how many hours did it take to get to 100 miles?
