Mark takes a job with a starting salary of P50.00 per hour. He was promised an increase of P5.00 per hour every three months for 5 years. What will be his wage per hour at the end of 5 years?

Sagot :

First we divide 5 years by 3 months. Note that 5 years is equal to 5*12=60 months.
[tex] \frac{60}{3} =20[/tex]
We multiply 20 by 5 and we get a product of 100.
Therefore his wage would be:
[tex]100+50=150[/tex]
P150
1 year=12 months
therefore
5 years=60 months

12/3 x 5
20 per year  will increase salary
100 per 5 years
Lets represent
f(t)=50+20t
where t is year
f(100)=50+5(20)
f(100)=150

Hope this helps =)
