Answer:
They made more at the spring concert because at the fall concert, they made 9/8 LESS then the spring concert. At the spring concert, they said they made 9/8 AS MUCH money. That indicates that they made more at the spring concert than the fall concert
Step-by-step explanation:
Let Amount of money made by School Orchestra at the fall concert=$ x
Then, Amount of money made by School Orchestra at the Spring concert
=9/8 as much money as they made at their fall concert
= 9x/8
=1.125x
Since, $1.125 x > $x
So, they made more money at Spring concert than Fall Concert.
