Answer:
The first option.
Because we're solving for the price of each gallon, x will represent the cost of each gallon. Since 8.4 is the total amount of gallons, multiply 8.4 and x to get $23.94. Solve for x by dividing 23.94 to get $2.85 per gallon. To check this, substitute 2.85 for x into the equation: 8.4 (2.85) = 23.94
18. Set the the two equations equal and solve.
F=x+25
b=x-3
x+b=25
b) x-3 +x =25
2x=25+3
x=28÷2
x=14
b= 11
f= 39
