The hourly wage of Cara after 3 years is given as $10.12.
An exponential function can be defined as y = aˣ. The value of the function at x = 0 is always 1.
Given that,
The wage of Cara per hour is $9.
The raise percent is 4%.
The given problem is the case of exponential growth.
The hourly wage after 3 years can be written in the form of expression as,
9(1 + 4/100)³
= 9 × (1.04)³
= 10.12
Hence, the hourly wage of Cara after 3 years is $10.12.

The ribbon required to be combined is 48 inches but he had only 36 inches. so, he does not have enough ribbons.
Given that,
Troy is making a flag-shaped like a square.
Each side measure 12 inches.
He wants to add a ribbon along the edges. He has 36 inches of ribbon.
We have to determine,
Does he have enoughribbon?
According to the question,
A square has 4 sides, and all sides have the same length.
If one side measures 12 inches, then the total length of all sides is,
= 4 × 12 inches = 48 inches
All edges combined are a total of 48 inches.
He only has 36 inches of ribbon, so he does not have enough ribbon.
Hence, The ribbon required to be combined is 48 inches but he had only 36 inches. so, he does not have enough ribbons.

set up equations
daren is 3 years older than tom
D = 3 + T
3 years ago leah will be 14 less than 3 times darren's age
L - 3 = 3(D - 3) - 14
L - 3 = 3D - 9 - 14
L = 3D - 9 - 14 + 3
L = 3D - 20
5 years ago, leah was 2 years less than 2 times tom
L - 5 = 2(T - 5) - 2
L - 5 = 2T - 10 -2
L = 2T - 10 - 2 + 5
L = 2T - 7
find leah's current age
set L = 3D - 20 and L = 2T - 7 equal to each other
3D - 20 = 2T - 7
plug 3 + T into D using the equation D = 3 + T
3D - 20 = 2T - 7
3(3 + T) - 20 = 2T - 7
9 + 3T - 20 = 2T - 7
T = - 7 - 9 + 20
T = 4
plug T back into L = 2T - 7 to find leah's current age
L = 2T - 7
L = 2 * 4 - 7
L = 8 - 7
L = 1
leah's age 4 years from now
add 4 to leah's current age
1 + 4 = 5
