From the question stem we get that Madge paid A dollars for R bananas, which means that her price per banana is \(\frac{A}{R}\), while Dean paid B dollars for S bananas, which means that his price per banana is \(\frac{B}{S}\).
To answer the question one needs to evaluate whether \(\frac{A}{R}\) or \(\frac{B}{S}\) is greater.
(1) B > AThis statement provides an inequality for the numerators of both fractions. While one numerator is larger than the other, their respective denominators, together with the numerators, will determine which fraction is bigger.
INSUFFICIENT(2) R > SThis statement provides an inequality for the denominators of both fractions. As with the previous statement, there is not enough information to determine whether Madge or Dean spent more per banana.
INSUFFICIENT(1+2)When used together, one sees that Dean's numerator is larger than Madge's, while his denominator is smaller than Madge's which means that his price per banana has to be higher than Madges.
SUFFICIENT
