Multiply the denominators to the LCF and subtract the numerators and then the whole numbers. You then simplify the fraction
Let's see here... the answer is C just by using common sense. A doesn't make sense because you can't cube .4, as it is a percentage, and you wouldn't add that to 1000. B makes no sense because the percentage you are using is 4%, not 30%. Of course, just be sure to fact-check me there.
Answer:
First table (far left)
Step-by-step explanation:
The far-left table is the only function with a constant rate. All other tables do not contain this.
To start off with $10.50 is 1050 cents. For the cleaning, he works 1 and 3/4 hours. That's $10.50 for one hour. $10.50/4 is $2.62 (rounded to a whole number.) Total: $13.12. For the paperwork, he works 2 and 1/3 hours. So that's $21 for 2 hours. $10.50 divided by 3 is $3.50. Total for paperwork is $24.50. For serving customers it's $10.50 for 1 hour. 10.50/12 is 87.5 cents so around 87 cents.. Total: $11.37. For the total earnings it is $13.12 + $24.50 + $11.37 = $48.99. (not that I have rounded all answers to whole numbers (you can't have a 1.5 cents for example)
