It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
6 boxes of blueberry muffins and 8 boxes of corn muffins
Since we know that each box has 18 muffins, we can multiply both 6 and 8 to determine the amount of muffins present
6 • 18 = 108 blueberry muffins
8 • 18 = 144 corn muffins
To determine the price, you multiply each type of muffin by 0.50 as each muffin is worth $0.50
108 • 0.50 = 54
144 • 0.50 = 72
You add these two together to get the price
54 + 72 = $126
If you explain what the estimate is, if I didn’t answer that along the way, I can help answer it for you.
The answers to the questions
I think it would be y=(-9/5)x -1/9
