How much fuel that sells for $1.25 per gallon must be mixed with 180 gallons that sells for $2.oo per gallon to obtain a mixture that sells for $1.55 per gallon? (i know i can say that x=gallons of $1.25 fuel, and x(1.25) + 180(2.oo) = something? i don't know what else to do!

Hello, Kim!
The "something" is the total value of the mixture.
There will be (x + 180) gallons of mixture, worth $1.55/gallon.
. . Total value: .1.55(x + 180)
And you already have an expression for the total value: .1.25x + 180(2.00)
And there is your equation: .125.x + 180(2.00) .= .1.55(x + 180)

You're certainly on your way . . .How much fuel that sells for $1.25/gallon must be mixed with 180 gallons that sells for $2.00/gallon
to obtain a mixture that sells for $1.55/gallon?
I know i can say that x = gallons of $1.25 fuel,
and: x(1.25) + 180(2.00) = something?
