Answer:
No, the rate is not proportional.
Step-by-step explanation:
If there are 45 marbles in 9 bags, we can assume that there are 5 marbles in each bag.
Going by that rate, we can do 5 * 36 = 180, NOT 150.
Thus, the rate is not proportional.
Another way to solve would be to do 45/9 and 150/36. If the rate is proportional, the answer for both should be the same.
However, 45/9=5 and 150/36=4.16666666667.
Those two answers are NOT equal.
Thus, the rate is not proportional.

Answer:
Frankie will need to babysit for 4.4 time.
Step-by-step explanation:
We are given the following in the question:
Money earned by Frankie each times he babysits = $5
Money saved = $30
Total money Frankie wants to save for a skateboard = $52
Amount of money to be saved =
Total amount of money Frankie wants to save for a skateboard - Money saved already
He needs to save $22 more.
Let x be the number of times Frankie will need to babysit.
Thus, we can write the equation:
Thus, Frankie will need to babysit for 4.4 time.
Answer:
The 12 egg offer.
Step-by-step explanation:
Find the unit price for each. Then make them common denominators. Like 3 eggs for 2 dollars is for 1 egg, 2/3 dollars. After getting the unit price for all of them, get the common denominators of 24. Then we see which numerator is the lowerst, since we want the lowerst price. We find 12/24, or the 12 egg offer.
