To answer the question above, let x the number of hours for the two jobs to cost equal. Harry's charge can be expressed as 70x + 130 and that of Lou is 80x + 40. Equating both,
70x + 130 = 80x + 40 ; x = 9
Thus, the job should take 9 hours for both charges to be equal.
Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
