Step-by-step explanation:
The cost for a group of 4 adults, 6 children, and 2 seniors to attend a performance can be calculated by substituting the respective numbers into the provided expression:
9.50a + 5.25c + 7.00s.
By substituting the given numbers of attendees into the expression
We get: 9.50(4) + 5.25(6) + 7.00(2).
Multiplying through, we find the cost to be:
9.50 × 4 = $38.00 for adults,
5.25 × 6 = $31.50 for children, and
7.00 × 2 = $14.00 for seniors.
Adding up these amounts gives us the total cost:
$38.00 + $31.50 + $14.00 = $83.50.
Therefore, the correct answer among the options provided, which is the real total cost for the group is $83.50. Option E.
