Answer:
$330 + $35h > $960
Step-by-step explanation:
To begin, you would multiply 3 by $110 since the plumber made that amount for each repair job and he had 3 repair jobs that day, giving an answer of $330.
Next, you would multiply h by $35 since that's how much he makes an hour and the h represents how many hours he worked.
Next step, add together the $330 and the $35h, which would just look like $330 + $35h.
Next would be the inequality sign. The problem explicitly states that his earnings equaled more than $960. Because of this, you would use a greater than sign, with the $330 + $35h being greater than the $960.
Finally, after writing it all down, you should get a final answer of $330 + $35h > $960.
Hope this helps!

Answer: 7 people need 16 minutes to paint 4 walls.
Step-by-step explanation:
Since we have given that it takes 63 minutes to paint 9 walls ,
So, we will apply "time and work formula" i.e.
where,
H denotes number of hours or minutes,
D denotes number of days
M denotes number of men
W denotes work done them,
So, we need to calculate number of minutes for 7 people to paint 4 walls,
So, 7 people need 16 minutes to paint 4 walls.
