Answer:
15 hours.
Step-by-step explanation:
We first need to see how much money Rose would earn if she sold the 10 pendents, so we will multiply 4×10.
4×10=40
Now we know, she already has 40 dollars of the 160 dollars she needs.
To find out how much she needs left, we will subtract 40 from 160.
160-40=120
She needs a total of 120 more dollars from working.
To find out how many hours she needs to work, we will divide 120 by 8.
120÷8=15.
In conclusion, she needs to work for at least15 hours to receive enough money.Please help me by marking this brainliest, and giving a thanks!
<span>Let C denote the number of candidates they interview and E the number of employees they train.
</span>
<span>If it takes 20 hours and $400 to interview a candidate, then it takes 20C hours and $400C to interview C candidates.
</span>
If <span>it takes 120 hours and $3600 to train an employee, then it takes 120E hours and $3600E to train E employees.
