The equation
____+ _____ a = ________
can help find out how many adults were in the group.

Answer 1

Answer:

There are 6 adults. My mistake! I had the wrong equation. 3 + 9a = 57.

Step-by-step explanation:

• There is only 1 child in the group.
• Cost for children is 3$.
• The cost for adults is 9$.
• 9 * 6 = 54
• 3 * 1 = 3
• 3 + 9a = 57
• Simplify:
• 6 Adults.

Answer 2

Answer:

3 + 9a = 57

(57-3) / 9

=54/9

=6

6 adults were in the group
