Multiply. Express your answer in simplest form. 5/8, 24

musickatia [10]

A number without denominator such is equal to number with denominator 1.
So, 24 is equal to 24/1

5/8 x 24

= 5/8 x 24/1

= (5x24) / (8x1)

= 120/8

= 15

mario62 [17]

Answer:

$\$63,163.16$

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 average annual salary

x is the number of years

r is the rate of change

a is the initial value

In this problem we have

$a=58,353\\r=2\%=2/100=0.02$

substitute

$y=58,353(1+0.02)^x$

$y=58,353(1.02)^x$

For x=4 years

$y=58,353(1.02)^4=\$63,163.16$
