Steven Davies · Answer 1

What do you mean by "1.2 times less potatoes"? Are you sure you have stated the problem correctly?

The formula for the number of potatoes at the first warehouse after x days is:

y = 210 + 90x

The formula for the number of potatoes at the second warehouse after x days is:

y = 180 + 120x

Then you need to relate these two functions using the statement "1.2 times less" which doesn't make sense. For example, if you had 1000 potatoes, what is "1.2 time less"?

It is 6 days. You have it right there.
