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

dimulka [17.4K]

Answer:

The correct answer is:

w-12 20

Explanation:

We first find the average of the two ends of the inequality:

(19.88+20.12)/2 = 40/2 = 20

This will be the number subtracted from w in the inequality.

Now we find the difference between this value and the ends:

20-19.88 = 0.12

20.12 - 20 = 0.12

This will be what our absolute value inequality ends with; the "answer" part, so to speak.

Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."

This gives us

w -12 20
