Answer:
400 + 6x
Step-by-step explanation:
$400 cabin cost is fixed and doesn't change.
Food cost changes as there are more people so we can write it as 6x
Total cost is 400 + 6x
As the 2 quadrilaterals are congruent the sides of one quadrilateral are equal to the corresponding sides of the other quadrilateral
Hence,
AB = PQ
RQ = BC
AD = PS
DC = RS
Since terms for both AB and PQ are given we can equate the terms and find m
5m -9 = m + 11
5m -m = 11 + 9
4m = 20
m = 5
Correct answer is D , 5

6x = 42
Division property of equality
6x/6 = 42/6
x = 7
