Answer:
2 hours
Step-by-step explanation:
Given: It takes Hank 
minutes 
hours to mow a lawn. Penny can mow the same size lawn in 
minutes 
hours. Hank and Penny form a small lawn care company and have contracts for 
lawns of the same size previously mentioned.
To Find: How long should it take both of them working together to mow the lawns.
Solution:
Time taken by Hank to mow the lawn 
Time taken by Penny to mow the lawn 
Total lawns to be mowed 
Let time taken by Hank and Penny to mow one lawn 
time taken to mow lawns 
Hence it will take 
by Hank and Penny to mow lawns

Step-by-step explanation:
x = the number of miles
y = the total cost
Company A:
0.60x + 60 = y [Company A charges $60 plus $0.60 per mile(x)]
Company B:
0.90x + 30 = y [Company B charges $30 plus $0.90 per mile(x)]
To find the number of miles where the costs for both companies are the same, you can set the equations equal to each other as the costs(y) are the same:
y = y Substitute the equations into "y" (substitute (0.60x + 60) and (0.90x + 30) into "y" since y = 0.60x + 60 and y = 0.90x + 30)
0.60x + 60 = 0.90x + 30 To find x, isolate/get the variable "x" by itself. Subtract 30 on both sides
0.60x + 60 - 30 = 0.90x + 30 - 30
0.60x + 30 = 0.90x Subtract 0.60x on both sides to get "x" on one side of the equation
0.60x - 0.60x + 30 = 0.90x - 0.60x
30 = 0.30x Divide 0.30 on both sides to get "x" by itself
100 = x 100 miles
(if you need to find out the cost where both companies cost the same, you can substitute/plug in the value of x into one of the equations.)
0.60x + 60 = y Plug in 100 into "x" since x = 100
0.60(100) + 60 = y
120 = y At 100 miles, both companies cost $120
