Question

For the following problem, identify the slope or rate of change and describe it in terms of the problem:

Answer 1

A is true. 50/20=2.5
b is true. 20 people come [every] three hours.
c is false. she isn't selling 1,600 if she has 100 berries left.
so C.

Answer 2

Answer with explanation:

Number of Strawberries that Sally owns at noon= 1,600 strawberries

At, 3 Noon

Number of customers who has purchased berries = 20

Number of baskets of berries sold = 50 baskets

Number of Strawberries left = 100

Within three hours

→ Number of baskets sold

               $=\frac{50}{20}=2 \frac{1}{2}$

Since ,within three hours there are 20 customers who has purchased berries .

So, slope of $\frac{20}{3}$ is an estimate of how many customers are in the field per hour.

→→Total number of strawberry sold =1,600-100=1,500

She is selling , $\frac{1,500}{3}=500$ strawberries(approximately) per hour.

→→In the starting ,there are 1, 600 strawberries,but at 3'O clock only 100 strawberries are left and 50 baskets of strawberries have been sold.

So, number of Strawberry in each basket

 $\frac{1,500}{50}=30$ .

⇒The False Statement is:

Option C. She is selling 1, 600/3 or an estimated 533 strawberries per hour.
