Sara has $150 in her savings account. The amount in her account increases by %6 every year. If she does not put more money into
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
