GenaCL600 [577]

Answer:

For more;

4.76

for less;

0.46

Step-by-step explanation:

Here, we intend getting the decimals that Carmen should make in her game given the numbers she drew

She has two types to make; a decimal less than 1 and a decimal more than 1

If the decimal should be less than 1, the number zero should lead;

And since she is using three of the numbers, we can have something like;

0.46

To make a decimal more than one, she could actually start with any of the numbers other than zero

we can have something like 4.76

A new car is purchased for 22300 dollars. The value of the car depreciates at 10.25% per year. What will the value of the car be
Roman55 [17]

Answer:

$11654 approx

Step-by-step explanation:

Given data

Principal amount =  22300 dollars

Rate= 10.25%

time= 6 years

The expression for the decrease is given as

A=P(1-r)^t-----------Note the negative sign is because of the decrease

substitute

A= 22300(1-0.1025)^6

A=22300(0.8975)^6

A=22300*0.5226

A=$11653.98

Hence the new value is $11654 approx
