Answer: 7 5/7 (the bottom one)
Step-by-step explanation:
30 divided by 2 = 15 (do the same to 42 and get 21)
This then creates the fraction: 15/21
Now, divide this fraction by 3 and get 5/7
Add back in the seven because you aren't dividing the whole number.
Your final answer is now 7 and 5/7 (together: 7 5/7)
Answer:
4 weeks
Step-by-step explanation:
Julie starts out $100 behind Amanda, but earns $25 per week more than Amanda. That means she will catch up after 100/25 = 4 weeks.
Lets x is the labor charges per hour
3x + 126.53 = 220.28
3x = 220.28 - 126.53
3x = 93.75
x = 93.75 / 3
x = 31.25
answer: $31.25 per hour charged for labor
