The exponential function will be the amount of the saving account after $75 is invested at a rate of 11% for x number of years. Then the correct option is D.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The first options are examples of the linear system.
The amount of the saving account after $75 is invested at a rate of 11% for x number of years is modeled as,
Amount = 75 (1 + 0.11)ˣ
Then the correct option is D.

Answer:
C. 32%
Step-by-step explanation:
First, you have to determine the amount they spent on entertainment and food:
Salary $2,700
Taxes: 10%: $270
Fixed expenses: $1,161
Savings: $405
$2,700-$270-$1,161-$405= $864
Alycia spent $864 on entertainment and food. Now, you have to find the percent of her income that this amount represents:
($864/$2,700)*100= 32%
According to this, the answer is that the percent of her income that was spent on entertainment and food is 32%.
Answer:
17
Step-by-step explanation:
let x be the number of boxes to be shaded to make it 80%
x = 80% of total number
= 80/100 of 25
= 80/4
= 20
So 20 need to be shaded to fill 80%
Now, 13 of the grids are already shared so the amount of more squares that need to be shaded = 20-13
= 17 squares
