She can wear outfits differently in 167 days.
Given that Lucy wants to wear different clothes everyday, and she has 8 dresses, 7 pairs of shoes, and 3 pairs of earrings, and Lucy can choose 1 dress, 1 pair of shoes, and 1 pair of earrings every day, but however 1 dress and 1 pair of shoes don't look good together, to determine, in such circumstances, how many days can she wear outfits differently, the following calculation must be made:
- (8 x 7 x 3) - 1 = X
- 168 - 1 = X
- 167 = X
Therefore, she can wear outfits differently in 167 days.

I am not sure if you have to use the substitution method but I just did (600 - 60) then divided by 4
Total interest will be $178245.
1. Earlier we were p[aying monthly $718.50( as per question 3 Now we are paying monthly $555.65
So we will save $162.85 ($718.50-$555.65) per month
2. Interest paid for previous loan for 10 years is $70888 Interest to be paid for next 30 years is $107357 Calculation of interest and other calculation is shown at last.
So total interest will be $70888+$107357 = $178245
3. Yes it viable to refinance it reduces interest burden and also save $162.85 everymonth. 1% difference in interest can save a lot money for us in long term and there is no extra cost for refinance hence it is really benificial.
4. Interest to be paid for the next 30 years will be $107357. You can calculate the interest as shown below as I am not able to upload the whole calculation.
