Adam bought \( a \) apples for \( \$ 1.50 \) each and \( b \) oranges for \( \$ 2 \) each. He spent \( 1.50 a+2 b \) dollars. What does \( 2 b \) represent? A the number of apples bought B the amount he spent on apples C the amount of both apples and oranges D. the amount he spent on oranges

To solve this problem, let's break down the information given: - Adam bought \( a \) apples for \( \$1.50 \) each. - Adam bought \( b \) oranges for \( \$2 \) each. - The total amount Adam spent is \( 1.50a + 2b \) dollars. Now, let's analyze what each term in the total amount represents: - \( 1.50a \) represents the total amount Adam spent on apples. Since each apple costs \( \$1.50 \) and he bought \( a \) apples, the total cost for the apples is \( 1.50 \times a \). - \( 2b \) represents the total amount Adam spent on oranges. Since each orange costs \( \$2 \) and he bought \( b \) oranges, the total cost for the oranges is \( 2 \times b \). Given this analysis, the term \( 2b \) represents: D. the amount he spent on oranges So, the correct answer is D. the amount he spent on oranges.
