Answer:

There would be 168 girls and 252 boys

Step-by-step explanation:

Answer: 252 Boys, 168 Girls

Step-by-step explanation:

420 would be 100% of the school students.

If you wanna find the number of girls, you need to divide 420/100 in order to get 1% and then multiply it by 40.

So then you would get

420/100 x 40 = 168

Then in order to get the boys just subtract 168 from 420

420- 168= 252

Thang decided to borrow $2000 from his local bank to help pay for a car. His loan was for 3 years at a simple intrest rat it 5%.
irakobra [83]

Answer:Thang will pay $300 as interest

Step-by-step explanation:

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 3 years

P = $2000

R = 5%

Therefore

I = (2000 × 5 × 3)/100

I = 30000/100

I = $300
