Answer:
Amounts in the intervall ![130 \leq c \leq 230](https://tex.z-dn.net/?f=130%20%5Cleq%20c%20%5Cleq%20230)
Step-by-step explanation:
We will take the variables c and s, where
c = amount to spend that month
s = savings of the month.
Since each month we save at least 100, we know that
![0 \leq s \leq 100](https://tex.z-dn.net/?f=0%20%5Cleq%20s%20%5Cleq%20100)
Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that
![250=20+s+c](https://tex.z-dn.net/?f=250%3D20%2Bs%2Bc)
and so
![230-s=c](https://tex.z-dn.net/?f=230-s%3Dc)
By multiplying by -1, the first inequality also tells us that
![-100 \leq -s \leq 0](https://tex.z-dn.net/?f=-100%20%5Cleq%20-s%20%5Cleq%200)
Consequently by adding 230 to the inequality, we get that
![230-100 \leq 230-s \leq 230\\\\\Rightarrow 130\leq c \leq 230](https://tex.z-dn.net/?f=230-100%20%5Cleq%20230-s%20%5Cleq%20230%5C%5C%5C%5C%5CRightarrow%20130%5Cleq%20c%20%5Cleq%20230)
180 eggs. That’s because 6 x 6 = 36 so we know how many eggs are in each tray. Then there are 5 trays with 36 eggs so 5 x 36 = 180
