Answer:
3 Hours
Step-by-step explanation:
Plumber A.
Initial fee: $45
Per Hour: $60
Plumber B.
Full rate: $225
To determine the number of hours it will take for both plumbers to charge the same amount you have to start with $45.
Then add 60$ every hour.
$45 + $60 = $105
$105 + $60 = $165
$165 + $60 = $225
Therefore, it takes 3 hours for them to charge the same rate.
The building would have to be 24 feet tall
36 inch is 3 ft
21/3=7
168/7=24
Question 4 Answer: 72/9=8 then you would 8x18=144 so it would take the person 2 hours and 24 minutes to deliver 72 newspapers.
