6 0

Answer:

36

Step-by-step explanation:

4 hours * (60 minutes)/(1 hour) = 240 minutes

We can use a proportion.

6 cars : 40 minutes = x cars : 240 minutes

6/40 = x/240

3/20 = x/240

20x = 3 * 240

x = 3 * 12

x = 36

Answer: 36

attashe74 [19]

Answer:

Compount interest earns more. Difference between 2 interest is $92 445.39

Step-by-step explanation:

Simple Interest:

I =  \frac{prt}{100}

p = $10000

r = 3%

t = 2years

I = (10000×3×2)/100

= $600

Total amount = $10 600

Compound Interest:

A = p( {1 +  \frac{r}{100}) }^{n}

p = $100000

r = 3/730 (daily)

t = 730 (2yrs)

A = 100000[1+(3/73000)]^730

= $103 045.39 (2d.p)

Difference = $103045.39 -

$10600

= $92 445.39
