Step 1) Convert $25 to a decimal:

0.25

Step 2) Multiply that by the amount the sandals cost.

$0.25×$45=$11.25

Step 3) Subtract from the amount you last got.

$45-$11.25=

$33.75

And there we have it! Our answer came out to $33.75.
So, with the 25% off, Sandy is now only paying $33.75 instead of $45.

Answer:

The answer is $33.75.

Step-by-step explanation:

First, find the amount of the discount by using the proportion, amount of discount divided by original price equals percent of discount divided by one hundred.Substitute the known values. Amount of discount divided by forty-five dollars equals twenty-five divided by one hundred.Then, cross multiply. One hundred times amount of discount equals twenty-five times forty-five dollars.Then, divide both sides by one hundred to get the discount amount of eleven dollars and twenty-five cents.Finally, subtract the amount of the discount from the original price. Forty-five dollars minus eleven dollars and twenty-five cents equals thirty-three dollars and seventy-five cents.

A pool pass costs $30 for the first month and $15 each additional month. Construct an explicit rule in function notation to mode
noname [10]

Answer:

F(n)=15(n+1)    [ where n is number of months]

F(12)=195

Step-by-step explanation:

Pool pass cost for first month =$30

Pool pass cost after first month = $15 for each month

The total amount charged by the pool can be expressed as a  function F(n) where n represents the number of months.

F(n)=15(n-1)+30

This can be simplified by using distribution.

F(n)=(15n-15)+30

F(n)=15n-15+30

F(n)=15n+15

Take 15 as greatest common factor.

∴ F(n)=15(n+1)

For n=12

F(12)=15(12+1)

F(12)=15(13)

F(12)=195

∴ Amount charged by pool for 12 months = $195

Find all numbers such that three times the number is greater than eight less than the number.
klio [65]

Answer:

ALL SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.

Step-by-step explanation:

Here, assume such number = m

Now, given :

3 times the number = 3 x ( m) = 3 m

8 less than the given number =  m - 8

Now, according to the question:

3 times the number  > 8 less than the given number

or, 3 m > m - 8

or, 3m  - m > m - 8 + m

or, 2  m > - 8

or, m > - 4

Hence, all SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.
