Explanation
Roselba’s income is more than twice as great as Jane’s income. If both pay the same percent of income in transportation fees, that means Roselba must pay more than twice as much as Jane in transportation fees. Quantity B is greater.
Alternatively, use smart numbers. Call Jane’s income $100. Roselba’s income, then, is greater than $200. If both pay 10% in transportation fees, then Jane pays $10 and Roselba pays more than $20.
Half of Roselba’s amount equals more than $10.
Hence B

R > 2J. Same %fee = r
We also have R/2 > J
Quantity A = J*r
Quantity B = 1/2*R*r > J*r = A
--> A < B
--> B
