1. Jim is buying donuts, each donut is $1.30 for every donut he buys, the price decreases by 5 cents, Jim buys 12 donuts. Linear, or non-linear? i think its linear pls help
Impatient much?
yes, it is linear.
See your previous post, and realize that posing it again will not make anyone happen to answer it any sooner. It just wastes time. For you to post it again, and for us to have to look at it again. In fact, if I see the same question posted many times in a short period, I tend to ignore it altogether.
ok, sorry
To determine if the relationship between the number of donuts purchased and the price is linear or non-linear, we need to analyze the pattern.
In this case, as Jim buys each donut, the price decreases by 5 cents. This means that for every additional donut he buys, the price decreases by a consistent amount.
Let's look at the price for each donut Jim buys:
1st donut: $1.30
2nd donut: $1.25 (a decrease of $0.05)
3rd donut: $1.20 (another decrease of $0.05)
...
12th donut: $0.75 (a total decrease of $0.55)
If we observe the pattern, the decrease in price for each donut purchase remains the same at $0.05. Hence, the relationship between the number of donuts purchased and the price is linear.
You can determine this by noticing that the price decreases by a constant amount, which is a characteristic of linear relationships. In this case, since the decrease is consistent, we can conclude that the relationship is indeed linear.
