I you use 1 gallon cost is 0.08(1) + 5 = 5.08
If 2 0.08(2) + 5 = 5.16 etc Increase is 0.08
For every extra 1 gallon the water increase is $0.08
Answer:
x = 5
Step-by-step explanation:
These triangles are similar, so they are in proportion to each other. Because of this we can say 
(the lengths of the vertical sides) = 
(the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.
Answer:
13 months
Step-by-step explanation:
x is the number of months
first phone:
f(x) = 55x + 100
second phone:
g(x) = 51x + 150
now set up the inequality
g(x)<f(x)
51x + 150 < 55x + 100
Solve the inequality:
51x + 150 < 55x + 100
(get everything on the correct sides... combine the like terms)
51x - 55x < 100 - 150
-4x < -50
divide both sides by -4 (don't forget to flip the inequality sign when dividing by a negative number.)
x > 50/4
x > 12.5
round up to 13
