Glenn Andrews recently bought a motorcycle for $3,950 if he had to pay 6% sales tax on the bike what was the total cost of the motorcycle?

Answers

Answer:

The total cost of the motorcycle is $4187 .

Step-by-step explanation:

As given

Glenn Andrews recently bought a motorcycle for $3,950 if he had to pay 6% sales tax on the bike .

6% is written in the decimal form.

$= (6)/(100)$

= 0.06

Sales tax price = 0.06 × 3950

= $237

Total cost of the motorcycle = Motorcycle cost + Sales tax price

= $ 3950 + $237

= $ 4187

Therefore the total cost of the motorcycle is $4187 .

60% converted 60/100= .06

$ 3950.00 x .06 = $237.00
3950.00
237.00
---------------
$4187.00 Total Cost of the Motorcycle

The list of multiples for 6 is infinite.
True or False?

Answers

Answer:

True

Step-by-step explanation:

As there are infinite numbers, the list of multiples are also infinite.

Multiples of 6 : 6, 12 , 18 , 24 ..............

Answer:

True; yes.

Step-by-step explanation:

Think about it, what does etc, etc mean? It means repetitive-a pattern, in a sort of way. So here are some multiples of 6:

6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96,102,108,114,120,126,132,138,144,150,156,162,168,174,180,186,192,198,204,210,216,222,228,234,240,246,252,258,264,270,276,282,288,294, etc.

As you can see, all I'm doing is adding 6 to every step I go. So when you say there is an infinite number, then these multiples are going to be infinite.
