Sagot :

1. 82% = Php 225.50

100% = Php original price (x)

225.50 = X

82 100

X = 225.50 x 100

82

X = Php 275.00

2. I = Prt

I = interest

P = principal value (initial value)

r = interest rate

t = time (year)

I = 30,000 x 0.6 x 1

I = 18,000

3. 10 pages per hour

6hrs for 5 days

6hrs x 5days x 10pages = 300 pages

4. 50,000 x 3/5 = 30,000

down payment = 30,000

5. 85.85 kg junshop materials
