Answer:
2.75x + 114 = 320.25
x = $75
Step-by-step explanation:
2.75x + 114 = 320.25
number of hours of labor (2.75) times the cost per hour of labor (x) + cost of parts (114) = total cost (320.25)
2.75x + 114 = 320.25
subtract 114 from both sides
2.75x = 206.25
divide both sides by 2.75
x = 75
------------------------
check the math:
2.75(75) = 114 = 206.25 + 114 = 320.25

The answer is 123
If bill rides his bike at an average speed of 5 mph it will take 13 hours
Step-by-step explanation:
9.94 => 10 (1s.f.)
29.7 => 30 (1s.f.)
Hence we estimate the value of 9.94² * 29.7
as 10² * 30 = 3,000.
