Question

The Okarche water department has a monthly service charge of $14.60 and a volume charge of $1.13 for every 100 cubic feet of water used. Which of the following equations can be used to determine the Savage family's monthly water bill?

(Let x represent the amount of water used, measured as indicated above, and y represent the monthly cost.)

Answer 1

@anusha.p @Callisto ?

Answer 2

what?

Answer 3

could you help with the question

Answer 4

Total amount = service charge + volume charge
total amount =y
service charge = 14.60
volume charge = (x/100 )(1.13)
Therefore,
y= 14.60 + (x/100 )(1.13)
= 14.60 + (1.13x/100)
Can you further simplify it?

Answer 5

@callisto,if the volume usage is less than 100 cubic feet.he won't be charged 1.13 dollars i thinkkk.

Answer 6

y = 1.13x + 14.60
y = 0.0113x + 14.60
y = 15.73x
y = 1.13x - 14.60
so which would it be

Answer 7

1.13 per every 100 cubic meter
so, 1.13/100 per cubic meter, that is 0.0113 per cubic meter
He uses x cubic meter
so volume charge = $0.0113x

@anusha.p I haven't said he will be charged 1.13 dollars if the volume usage is less than 100 cubic feet :|

Answer 8

@selenamalter you cannot add the 2 terms :|

Answer 9

so its B

Answer 10

of course @Callisto .i just got confusedd,if it is not charged when the usage is less than 100 ft^3.

Answer 11

@selenamalter What do you mean?
BTW, is the vol. of water measured in 100 cub. meter?

Answer 12

i sent the answer options

Answer 13

@anusha.p mathematically, that is the equation... I don't know what the real case is, as I'm not the one who responsible for paying the bills..

Answer 14

K.LOL

Answer 15

@selenamalter you haven't mentioned there are choices. but it must not be -14.60 ... it should be + 14.60 :|
