Sean bought 1.8 pounds of gummy bears and 0.6 pounds of jelly beans and paid $10.26. He went back to the store the following wee

Ymorist [56]

Answer:

Gummy bears $3.20/lbs

Jelly beans $7.50/lbs

Step-by-step explanation:

For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):

1.8x + 0.6y = 10.26

1.2x + 1.5y = 15.09

Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)

Use the recursive formula f(n) = 0.5 ⋅ f(n − 1) + 10 to determine the 2nd term if f(1) = 4.

Nikitich [7]

Answer:

Option B. f(2) = 12.0

Step-by-step explanation:

we have

$f(n)=0.5f(n-1)+10$

we know that

The second term is f(2)

For n=2

substitute the value of n in the formula

$f(2)=0.5f(2-1)+10$

$f(2)=0.5f(1)+10$

we have

$f(1)=4$

substitute

$f(2)=0.5(4)+10$

$f(2)=12.0$
