Interpretation of Fruit Purchase

Medium Heart Of Algebra Linear Equations And Inequalities

A store sells apples at $0.50 each and oranges at $0.75 each. A customer buys a total of 20 fruits and spends a total of $12.50 on apples and oranges.

If $a$ represents the number of apples purchased and $o$ represents the number of oranges purchased, which of the following systems of equations can represent the situation?

$$a + o = 20$$<br>$$0.5a + 0.75o = 12.5$$

$$a + o = 12.5$$<br>$$0.5a + 0.75o = 20$$

$$0.5a + o = 20$$<br>$$0.75a + o = 12.5$$

$$a + o = 10$$<br>$$0.5a + 0.75o = 25$$
