Work Step by Step

Step 1) 75 cents per hour = .75 dollars an hour ... Because there are 100 cents in 1 dollar, we can cross cancel to rid the 'cents' from the equation and only have 'dollar' remaining. Note that this is now in 'dollar/hour' format. We still need to get it to dollar/day format. Step 2) .75 dollars an hour x 24 hours = $18 dollars a day ... Because there are 24 hours in 1 day, we can cross cancel to rid 'hours' from the equation. Now, we have it in the correct format of 'dollar/day'.
