If you do 50 times 4 it’s easier to find 500 times 400 because all you have to do it add 3 more zeros behind 200 making the answer be 200,000.

Answer/step-by-step explanation:

Well, we know that 50 x 4 = 200.

We also know that 4 x 100 = 400, and 50 x 10 = 500.

Therefore, in order to find the answer to 500 x 400, we need to multiply 200 by 1000, or 100 x 10.

200 x 1000 = 200,000

Therefore, 500 x 400 = 200,000.

Hope this helps! :D

A man purchased a car selling for RM12,750 by making instalment payments. If he was charged 4% based on the reducing balance and
a_sh-v [17]

Answer:

48 months

Step-by-step explanation:

Cost of car = RM12,750

interest charged = 4% = 0.04

total interest paid = RM1,041.25

Now,

Using the Constant Ratio formula

r = \frac{24\times\textup{i}}{\textup{P(n+1)}}

here,

i is the interest paid

P is the principle

n is the number of monthly installments

r is the interest rate

on substituting the respective values, we get

0.04 = \frac{24\times\textup{1041.25}}{\textup{12,750(n+1)}}

or

n + 1 = 49

or

n = 48 months
