Answer:
$ 584.89
Step-by-step explanation:
so each student is responsible for selling 12 necklaces...and there are 130 students....so thats (130 * 12) = 1560 necklaces
each necklace is 1.50....so thats (1560 * 1.50) = 2340
profit = revenue earned - expenses
profit = 2340 - 0.45 = 2339.55
1/4 of the profit goes to Puerto Rico
1/4 * 2339.55 = 2339.55/4 = 584.887 rounds to $ 584.89 <==

Step-by-step explanation:
y = 400 × 0.75
y = 300
300 milligrams = 0.75 hours
x = 3 hours
3(300) = 0.75x
900 = 0.75x
x = 1200
13 is 10% of 130.
You want to multiply 13 x 10 = 130
It's called the least squares method because the parameters of the regression line are adjusted in such a way that the sum of squares of the difference (between the actual and predicted values) is a minimum.
