Before starting her shift, a waitress checks to make sure there is enough mustard for her customers. She finds \( 1 / 2 \) of a bottle at the first table, \( 1 / 2 \) of a bottle at the second table, \( 7 / 10 \) of a bottle at the third table, and \( 1 / 2 \) of a bottle at the fourth table. Altogether, how many bottles of mustard does the waitress find? Bii

To find out how many bottles of mustard the waitress has altogether, we need to add the amounts she found at each table: - At the first table: \( \frac{1}{2} \) - At the second table: \( \frac{1}{2} \) - At the third table: \( \frac{7}{10} \) - At the fourth table: \( \frac{1}{2} \) First, we can convert the \( \frac{1}{2} \) amounts to tenths for easy addition: - \( \frac{1}{2} = \frac{5}{10} \) Now, we can rewrite the sums: - First table: \( \frac{5}{10} \) - Second table: \( \frac{5}{10} \) - Third table: \( \frac{7}{10} \) - Fourth table: \( \frac{5}{10} \) Now let's add: \[ \frac{5}{10} + \frac{5}{10} + \frac{7}{10} + \frac{5}{10} = \frac{22}{10} \] To convert it to a mixed number, \( \frac{22}{10} \) simplifies to \( 2 \frac{2}{10} \) or \( 2 \frac{1}{5} \). Thus, the waitress finds a total of \( 2.2 \) bottles of mustard or \( 2 \frac{1}{5} \) bottles.
