Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Total Amount made = $250
Amount charged = $70 per car
Tips earned = $50
Equation 1 to represent the above
(Amount charged per car × number of cars) + tips earned = total amount made
Let number of cars = c
Hence,
$70c + $50 = $250
Part B:
Total Amount made = $250
Amount charged = $75 per car
Tips earned = $35
Cost of supplies per car washed = $5
Equation 2:
(Amount charged per car × number of cars) + tips earned - (cost of supplies × number of cars) = total amount made
$75c + $35 - $5c = $250
$70c + $35 = $250
C) Equation 1 does not include the cost incurred in getting the car washed while equation 2 takes into account the cost incurred in washing a car which is then subtracted from the amount charged per car. Also the tips earned in equation 1 is $50 while equation has a tips fee of $35

Answer:
Step-by-step explanation:
radius 70/2=35 cm
circumference=2πr=2π×35=70π cm
time taken to complete one revolution=0.8 s
or distance covered in 0.8 s=70π
distance covered in 1 s=70π/0.8=700 π/8=175 π/2 s=87.5 π≈274.9 cm
speed=274.9 cm/s=2.749 m/s
