Answer:
The total number of couples attending the banquet was 52.
Step-by-step explanation:
Given that a school reserved a banquet hall for the spring dance, and that, in addition to a $ 100 deposit, each couple must pay $ 20, to determine the total number of couples attending if the total cost of the banquet hall was $ 1,140 is due perform the following calculation:
100 + (20 x X) = 1140

X = 1040/20
X = 52
Thus, the total number of couples attending the banquet was 52.
