Answer:
Your friend made 35 bird houses.
Step-by-step explanation:
If the ratio from your houses to your friends houses is 4:5, that means that for every 9 houses built, your friend did 5. So, every 18 houses built, your friend did 10. For every 27, your friend did 15, and for 36, your friend did 20, and for every 45, your friend did 25, and for every 54, your friend did 30, and for every 63, your friend did 35.

Answer:</h3>
5 Adults; 6 Children
<h3>
Step-by-step explanation:</h3>
If all the tickets purchased were child tickets, the cost would be 11×$35.95 = $384.45. The actual cost is $434.45 -384.45 = $50 more than that.
Changing a child's admission to an adult's admission adds $10 to the cost, so there must have been $50/$10 = 5 adult admissions in the mix. Of course, 11 - 5 = 6, the number of child admissions.
The families bought 5 adult tickets and 6 child tickets.
_____
<em>Using an equation</em>
Let x represent the number of adult admissions. Then 11-x is the number of child admissions, and the total cost is ...
... 44.95x + 34.95(11 -x) = 434.45
... 10x = 50 . . . . . . . . subtract 384.45 and simplify (compare to the above)
... 50/10 = x = 5 . . . . the number of adult admissions
It is 9 because 11 minus 2 is equal to 9.
