in and cash out when its value reaches $1,000. Over the last 12 months, you ve seen the value of the Bytecoin grow exponentially at a rate of 15% per month! You want all of your friends and family to invest with you, but you need to make predictions about how long it will take for your $243 investment to earn $1,000.

Answer:

Step-by-step explanation:

The growth rate of the coin is exponential. We would apply the formula for exponential growth which is expressed as

y = ab^x

y = b(1 + r)^ t

Where

y represents the value of the coin after x months.

x represents the number of months.

a represents the initial value of the coin.

b represents rate of growth.

From the information given,

a = 243

b = 1 + 15/100 = 1 + 0.15 = 1.15

Therefore, the exponential expression to determine the number of months, x it will take for the coin to attain a certain value, y is expressed as

y = 243(1.15)^x

If y = 1000, it means that

1000 = 243(1.15)^x

1000/243 = 1.15^x

4.115 = 1.15^x

Taking log of both sides, it becomes

log 4.115 = xlog1.15

0.614 = 0.061x

x = 0.614/0.061

x = 10 months

It will take 10 months

Sybille makes and sells candles for her Possible Project business. Sybille sells multi-scented candles for $3 each and single-sc
trasher [3.6K]

Answer:

24 multi-scented candles

10 single-scented candles

Step-by-step explanation:

There was no question, so I am going to assume that you want to know how many of each type of candles were sold.

Let m = no. of multi-scented candles

     s = no. of single-scented candles

(1)      m + s = 34             (2)   3m + 2s = 92      

               s = 34 - m              3m + 2(34 - m) = 92

                                              3m + 68 - 2m = 92

                                                  m + 68 = 92

                                                           m = 24

              s = 34 - 24 = 10

lawyer [7]

Answer:

y intercept = 4

x intercept = -8

Step-by-step explanation:

0 = x/2 + 4

-4 = x/2

-8 = x

y=mx+b

y = 1/2x+4

Y intercept = b, b= 4

Raphael paid $664 for camera during a 60% off sale. What was the camera's regular price? I need to see work to understand. Thank
jonny [76]
664=60% off of original

percent means parts out of 100
60%=60/100=0.6

664=60% of original
'of' means multiply
translate

664=0.6 times originail
divide boh sides by 0.6
1106.666666=original
about $1106.67=original
or you could do ratio and proportion
664/60=x/100

answer is still $1106.67
