It was a 5 percent change because if you subtract 460 form 483 you will get 23, then you need to divide 23 by 460. You will get 0.05. You need to multiply that answer by 100 to get 5

You earn $250 per month from your part-time job. You are in a kayaking club that costs $20 per month, and you save at least $100
Olegator [25]

Answer:

Amounts in the intervall 130 \leq c \leq 230

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

Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that

250=20+s+c

and so

230-s=c

By multiplying by -1, the first inequality also tells us that

-100 \leq -s \leq 0

Consequently by adding 230 to the inequality, we get that

230-100 \leq 230-s \leq 230\\\\\Rightarrow 130\leq c \leq 230
