Answer:
300 liters
Step-by-step explanation:
If he uses 15, 2 liter bottles in a week,
then 15 * 2 = 30 liters in a week.
If he uses the same rate in 10 weeks then,
10 * 30 = 300 liters
Sort the data by x:
(26,31),(29,28), (33,25), (38,21),(45,18),(49,17),(55,15), (62,13),(64,13), (72,11), (92,9)}
That look like an obvious decreasing trend. From the first and last point we get a slope of (9-31)/(92-26) = -1/3 and a y intercept of 31 - (-1/3)26 = 39.67.
That's pretty close to Choice d y=-3/10x+35
Answer: d
the answer would be 2985000x
