Suppose a household's monthly water bill ( in dollars) is a linear function of the amount of water the household uses in hundred of cubical of feet (hcf) when graphed the function gives a line with a slope of 1.45. if the monthly cost is 18hcf is $46.50 what is the cost for 12hcf

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
