I assume you meant to type the following:
3/(5k-5) = 7/100
When we multiply both sides by (100)(5k - 5), we get this:
300 = 7(5k - 5)
300 = 35k - 35
300 - 35 = 35k
265 = 35k
265/35 = k
Answer:
A university president's salary for 2012-2013 academic year was $452,000. Calculate his 2013-2014 salary if he received a 2.8% raise
452,000×1.028=464,656
1 - 7 + 7 + 3 + 3 = 20
2 - 3 + 3 + 4 + 3 = 13
3 - 7 + 7 + 2 + 2 = 18
4 - 2 + 2 + 9 + 9 = 22
5 - 3 + 1 + 3 + 1 = 8
20 + 13 + 18 + 22 + 8
33 + 18 + 22 + 8
33 + 18 + 30
63 + 18
= 81
