Answer:
Step-by-step explanation:
Give the data
198 sq.yd × 8 sq ft ×7
Note that we have two unit of measurement which are yd and ft and 7 is just a constant
So we need to convert them,
Then, 1 yd = 3ft
Also notice that they are square.
Then square both sides of the comparison
(1 yd)² = (3 ft)²
1 sq.yd = 9 sq.ft
Then, back to our question,
198 sq.yd × 8 sq ft ×7
Let covert to ft
198 sq.yd× (9 sq.ft/1 sq.yd) ×8 sq.ft×7
sq.yd cancels out
99,792 sq.ft × sq.ft
99,792 ft⁴
Let convert to yd
198 sq.yd × 8 sq ft ×7
198 sq.yd×8 sq.ft (1 sq.yd / 9sq.ft )×7
1,232 sq.yd × sq.yd
1,232 yd⁴
25$ is the flat fee. 50$ is the amount charged per hour. Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.
C=25+50h
To find the amount of money for 8 hours simply plug in 8 for h and you get 400. Don't forget to add the flat fee of 25. The total cost for 8 hours of service is 425.
To find the amount of money for 10 hours of work, plug in 10 for h and you get 500. Add 25 to 500 and you get 525 for a total of 10 hours of work.
Hope this helped...
