Answer:
the large arrangement be 21
Step-by-step explanation:
The computation of the large arrangements she delivered is as follows:
Let us assume the small arrangement be x
And, the large arrangement be y
Now as per the question
5.50x + 8.25y = $343.75 ......(1)
x + y = 52........(2)
We can write as
x = 52 - y
Now put the x value in the (1) equation
5.50(52 - y) + 8.25y = $343.75
$286 - 5.50y + 8.25y = $343.75
2.75y = 57.75
y = 21
Hence, the large arrangement be 21
