Exponential growth

y=(1+r)t power

the original value of an investment is $1400 and the value increases 9% each year. write an exponential growth function to model this situation. then, find the value of the investment after 25 years.

answer: 15

step-by-step explanation:

80% of the cookies

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
