1. Rachel can read a 380-page novel in 4 hours.At this rate,how many pages will she have read if she has been reading for 1 1/2 hours?

Solution:

380/4 = x/(1 1/2)

380/4 = x/1.5

380(1.5) = 4x

570 = 4x

570/4 = x

x = 142.5 pages

2. Laura deposits Php 10 000 at 6% annual interest. How much interest will it gain in 3 years and 9 months?

Solution:

t = 3 years and 9 months = 3 + 9/12 = 3.75 years

r = 6% = 6/100 = 0.06

A = P(1 + rt)

A = 1000(1 + 0.06(3.75))

A = 1000(1 + 0.225)

A = 10000(1.225)

A = 12250 php

Interest = A - P

I = 12250 - 10000

I = 2250 php
