2) At a local grocery store, three bags of peanuts and four bags of almonds cost $27 45.
Scilla [17]

Answer:

$7.60

Step-by-step explanation:

Use a linear function (again)

let x = peanuts

let y = almonds

3x+4y=27.45

5x+2y=24.05

Multiple 2nd equation by 2

3x+4y=27.45

10x+4y= 48.1

7x=20.65

x=2.95

Plug in x into either equation

10x+4y= 48.1

29.5+4y=48.1

4y=18.6

y=4.65

4.65+2.95=7.60

Hence we can say , the number of bacteria after n month can be given using the exponential growth function

a_n=4*3^n

So number of bacteria after 15 month will be

a_{15}=4*3^{15}
