Missing part

40 new subscribers joined

$1150

Step-by-step explanation:

Initially, the number of subscribers was 200 and when 10 cancel their subscription, the remaining subscribers will be 200-10=190 subscribers. Since 40 more also subscribe, then the total subscribers will be 190+40=230 subscribers.

Now since each subscriber pays $5 monthly then for that month, the earning will be $5*230 subscribers=$1150.

Therefore, for that month, the earnings will be $1150
