Answer:

y = 1500 - 75t

It will take her 20 months to pay off her TV loan.

Step-by-step explanation:

Vanessa purchased a smart TV for $1500 on a payment plan.  After 4 months of purchasing the TV her balance was $1200 . 7 month her balance was $975.  The amount she pays every month can be calculated as follows. After 4 months she paid 1500 - 1200 = $300. Her balance is $1200. Divide 300 by 4 to get $75 per month as the amount she pays every month.

1500 - 975 = 525/7 = $75 per month.

The equation to model the balance y after t months can be expressed below.

y = 1500 - 75t

where

y = balance

t = number of months

Her balance should be $0 for her to be able to pay off the TV loan.

y = 0

-1500 = -75t

divide both sides by -75

t = -1500/-75

t = 20

It will take her 20 months to pay off her TV loan.

A candy store held a contest to guess the total number of jelly beans in a jar. All of the jelly beans in the jar were either gr
Fudgin [204]

Answer:

Step-by-step explanation:

Let the number of orange jelly beans be x , as we do not know the exact value of it yet. There are 12 times as many green jelly beans than the orange ones. So , if the number of orange jelly beans is x , the number of green jelly beans will be = 12 times x , which can be written as 12x. Now there are a total of 1872 jelly beans , but they are either orange or green , so we already know that the number of orange jbs is x , and the number of green jelly beans is 12x. So if we the green jelly beans and orange jelly beans , it should be 1872.

Now all we need to do is to find x.

We know that ,

x + 12x = 1872

Now we add x and 12x on the left hand side

13x = 1872

Now we divide both sides by 13 to get x. (That includes 1872 as well)

x = 144

Now we have the value of x which is 144

We know that the number of green jelly beans was 12 times x

So the number of green jelly beans in numeric value is : 12 * 144

As x is equal to 144

Ans . : The number of green jelly beans is 1728.
