Question

Find slope or rate of change from this table.
x (number of items purchased) y (total cost)
$5 $35
$10 $60

Answer 1

To find the slope or rate of change from the table, we first need to calculate the change in y with respect to the change in x.

For the first set of data:
Change in y = $60 - $35 = $25
Change in x = $10 - $5 = $5

Therefore, the rate of change is $25 / $5 = $5 per item.

So, the rate of change for the first set of data is $5 per item.

For the second set of data:
Change in y = $35
Change in x = $5

Therefore, the rate of change is $35 / $5 = $7 per item.

So, the rate of change for the second set of data is $7 per item.
