(a) what is a good scale to use for the y-axis? explain your reasoning. (b) what is a good interval to use for the y-axis? explain your reasoning.

Step-by-step explanation:

According to the given statement:

A family is tracking its spending habits. Over the past year, the grocery bill has ranged from $120 to $180

a) What is a good scale to use for the y-axis.

As the range is from $120 to $180 then 20 units will be a good scale to use because 120 and 180 both are divisible by 20

Thus 1 scale = 20 units

b)  What is a good interval to use for the y-axis

Again it will be of 20 units

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
