Question

A teacher already had a certain number of canned goods for the food drive. Each day of the food drive, the class plans to bring in 10 cans. The total number of canned goods for day 10 is 205. Assume the relationship is linear. Find and interpret the rate of change and the intitial value .

Answer 1

Answer:

Initial value: 115

Rate of change: 10

Step-by-step explanation:

Here we can see that the total number of canned goods for day 10 is 205. And each day class plans to bring 10 cans.

So for the other 9 days class must have brought 90 cans. If on day 10 the total number of canned goods is 205 then on the first day, teacher must be having,

$205-90= 115$ cans of food.

So the initial value is 115.

Since the class is bringing 10 cans a day, that is the rate of change. Each day the consumption is of 10 cans. Or we can say 10 cans per day so that is the rate of change.
