Answer:
2.22 hours
Explanation:
If Sally can paint the office by herself in 5 hours, we can say that in one hour she paints 1/5 of the office.
On the other hand, Lucy paints the office in 4 hours, which means that, in 1 hour she paints 1/4 of the office.
Therefore, to know how much they would paint per hour working together, we are going to sum up the fractions they paint per hour:
Therefore, working together they will paint 
of the office in one hour.
Now we can establish a rule of three: if they paint 0.45 of the office in 1 hour, how long (x) will it take them to paint 1.0 of the office?
And therefore 
Therefore, it will take them 2.22 hours to paint the office working together.

Truth in Lending Act is the federal law that requires the cost of credit be disclosed to consumers in bold print on loan agreement
<h3><u>
Explanation:</u></h3>
The Truth in Lending Act (TILA) passed in 1968 to take care whether the consumers are treated fairly by revealing about the true cost of credit. The credit documents should be made very clear to the consumers. It does not place limitations on banks about how enough interest they may impose or whether they must give a loan.
This TILA statement includes annual percentage rate, schedule of payment and finance charges and the repayment within loan lifetime. Regulation Z is alternative name for Truth in Lending Act. Both the terms can be used in all aspects of lending and credit card purposes.
