Currently, the number of people entering a shopping mall is 109. It is estimated that the number of people entering the shopping

Answer:

96 people.

Step-by-step explanation:

Exponential equation for a decreasing amount:

The exponential equation for a decreasing amount is given by:

$A(t) = A(0)(1-r)^t$

In which A(0) is the initial rate and r is the decay rate, as a decimal.

Currently, the number of people entering a shopping mall is 109.

This means that $A(0) = 109$

It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.

This means that $r = 0.03$

$A(t) = A(0)(1-r)^t$

$A(t) = 109(1-0.03)^t$

$A(t) = 109(0.97)^t$

Find the total number of people entering the shopping mall at the end of 4 hours.

This is A(4). So

$A(4) = 109(0.97)^4 = 96.49$

Rounding to the nearest whole number, 96 people.

How do you solve the system of equations 4 x − 2 y = 1 and -4 + 4 y = -2

Dmitrij [34]

Answer: y= -2 - 1/2

Step-by-step explanation:

-4x -2y = 1

+4x +4x

-2y = 4x + 1

/-2 /-2 /-2

y= -2 - 1/2

I think, i may be incorrect but the verbal explanation is; -4x is needed to be moved so you add 4x to both sides and 4x cancels out on the left which leaves -2y on the left (when it was moved "x" is always first). then divide all numbers by -2 to get y by itself. this gives you y= -2 - 1/2 if my calculations are correct.
