NEW question from GMAT® Official Guide 2019
(PS13159)
Since the price of gasoline goes up from $1.65 to $1.82 from last week to now,
the amount that Sally spends on gasoline also goes up by a similar margin.
As, 1.65 -> 26.40 | 1.82 -> x(amount Sally spent on gasoline)
\(1.65 * x = 26.40 * 1.82\) ->\(x = 26.40 * \frac{1.82}{1.65} = $29.12\)
Therefore, Sally spends \($29.12 - $26.40 = $2.72\)
(Option D) more on gasoline this week.
