Mr. Murphy's Megan graph to show his class the amount of water person consumes from food and beverages over time. a person consumes 12 gallon of water each day (i already answerd this part)

(this part is the one im asking about )
complete the equation to show the relationship between X the number of days and Y the amount of water consumed
Y = ? X​

y = 12x

Step-by-step explanation:

From the question, we are told that a person consumes 12 gallons of water each day

Now, we want to complete an equation

From the question, x is the number of days and y is the amount of water consumed

Thus, mathematically, we have the equation as;

y = 12x

since in the first day, 12 gallons is consumed, the second will be 12 * 2 and so on

So the amount of water depends on rate number of days

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
