State whether the graph of each linear relationship is a solid line or a set of unconnected points. Explain your reasoning. 1. The relationship between the height of a tree and the time science the tree was planted
2. The relationship between the number of $12 DVDs you buy and the total cost

Ithink the answer is $2.10

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
