Let x = Craig's time
Let y = Tom's time
Create a system of equations to solve this problem.
8 = x + y
y = 4x
Substitute 4x into the y variable in the first equation.
8 = x + 4x. Combine like terms
8 = 5x. Divide each side by 5.
1.6 = x
Craig takes 1.6 hours to clean the house
Answer:
1 Hour
250 + 150h = 500
Step-by-step explanation:
So, the fee for the meeting is 250. The hourly fee is 150. Let h equal the number of hours.
250 + 150h
If pablo has 500, then we cannot exceed that amount. So, our equation becomes
250 + 150h = 500
Subtract 250 from both sides
150h = 250
And divide by 50 on both sides. You get x = about 1.67. Since this is a question about time and money, you would round down to 1.
