formula

[dh_007]

I need to make a formula for the following paragraph

The per gallon price of gas is determined wiether the customer purchases leaded or unleaded.
A federal gasoline tax is applied to each gallonof gas, varying by weither its leaded or unleaded. If the customer pumps gas themselves there no additional fees apart from sales tax. if they have a representative pump gas for them one of the 2 charges apply

gas-n-go - the station pumps gas but no other service is performed. a fixed price is added to bill and charge dose not vary by how much fuel us purchased.

full service - the station pumps gas, checks oil, etc . a fixed price is added to bill and charge dose not vary by how much fuel us purchased.

a state sales tax is applied to the sum of all charges except for federal gasoline tax.

Sorry...do you know someone who could rewrite that in proper English?

proper english this is exacly the way it is from the paper

I just want the paragraph form put in formula form such as you read about a houses length and width to claculte the area. the formula for that would be:

Length * width = area

I don't believe it.

I have 15 minutes to spare, right now, so I'm willing to try interpret this mess. Here's my best guess.

Start by assigning symbols to represent the variable and seven constants.

G = GALLONS pumped

L = leaded PRICE per gallon

U = unleaded PRICE per gallon

A = gas-n-go service FEE

B = full service FEE

S = sales tax RATE

X = federal TAX PER GALLON for leaded gas

Y = federal TAX PER GALLON for unleaded gas

Here are three example scenarios; I'll leave the remaining possibilities for you to write.

G gallons of unleaded gas pumped with gas-n-go service:

UG = cost of gas only

UG + A = taxable subtotal for sales tax

S(UG + A) = sales tax

YG = federal tax

TOTAL = UG + A + S(UG + A) + YG

G gallons of leaded gas pumped with full service:

LG = cost of gas only

LG + B = taxable subtotal for sales tax

S(LG + B) = sales tax

XG = federal tax

TOTAL = LG + B + S(LG + B) + XG

G gallons of leaded gas pumped by customer:

LG = cost of gas only

S(LG) = sales tax

XG = federal tax

TOTAL = LG + S(LG) + XG
