Answer :
Wage Elijah earns for an hour's work = $10
Wage Elijah earns per subscription = $2
Wage Pablo earns for an hour's work = $5
Wage Pablo earns per subscription = $3
To find the number of subscriptions they both made in an hour such that both of them have the same amount of money worth them , let is find the LCM of 2 and 3 .
LCM of 2 and 3 = 6
Therefore , Elijah and Pablo must have made 6 subscriptions to end up earning the same amount in an hour .
