The water rate in a village in westchester county is $3.74 per 100 cubic feet used. What is the water bill if the resident uses 800 cubic feet?

$29.92

Step-by-step explanation:

For every 100 cubic feet, $3.74 is charged

If a resident uses 800 cubic feet, then we multiply the rate by 8 since 800 is 8 times 100.

3.74 x 8 = 29.92

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
