strojnjashka [21]

Answer:

$159

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

y=a(1+r)^x

where

y is the balance in the saving account

x is the number of years

a is the initial amount

r is the percent rate of change

we have

a=\$150\\r=6\%=6/100=0.06

substitute

y=150(1+0.06)^x

y=150(1.06)^x

For x= 1 year

substitute

y=150(1.06)^1=\$159

31. At the candy store: => Ericka bought 3 kilograms of Cinnamon red hots and 1 kilograms of gummy bears for 21.00 dollars. => Irene bought 3 kilograms of cinnamon red hots and 3 kilograms of gummy bears for 39.00 dollars. Question: Find the costs of each kilograms. Notice that the cinnamon red hot that they both are the same, the only difference is the gummy bears, which added 2kilos for Irene. Now, let’s subtract => 39 – 21 = 18 dollars – this is the costs of 2 kilos of gummy bear => 18 / 2 = 9 dollars, thus the price of each kilos of gummy bear is 9 dollars, Now, let’s solve for the cinnamon => 21 – 9 = 12 dollars, to be divided with 3 kilos => 12 / 3 = 4 dollars – the price of cinnamon red hot per kilo.
