Understanding Savings and Expenditure

The video tutorial explains how to determine Dante's original savings using two methods: geometric and algebraic. Initially, Dante spends two-thirds of his savings on a car and a quarter of the remaining savings on a phone costing $250. The geometric method involves visual partitioning of savings, while the algebraic method uses equations to solve for the original amount. Both methods conclude that Dante's original savings were $3,000.

What fraction of Dante's savings was spent on the used car?

• 1/3

• 2/3

• 1/4

• 1/2
