Answer:

4 hours and 30 minutes

Step-by-step explanation:

set the equation

y=10x+5

y= the total amount of money it will cost, x= the hours they spend on your lawn

substitute 50 for y

50=10x+5

45=10x

x= 4 and a half hours
They could spend 4 which is 40 and they charge 5$ travel fee so the total would be 45$ altogether
good job
