Let C = cost to rent each chairLet T = cost to rent each table
 4C + 8T = 73 
2C + 3T = 28 
Multiply the 2nd equation by (-2) and then add the equations together 
  4C + 8T = 73
-4C - 6T = -56
 2T = 17T = 17/2 = 8.5
 Plug this in to the 1st equation to solve for C
 4C + 8(17/2) = 73
4C + 68 = 73
4C = 5C = 5/4 = 1.25
 So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50

Step-by-step explanation:
 
        
             
        
        
        
The population size after 6 years and after 8 years are 147 and 169 population respectively
<h3>Exponential functions</h3>
The standard exponential function is expressed as y = ab^x
where
a is the base
x is the exponent
Given the function that represents the population size P (t) of the species as shown;

For the population size after 6 years

For the population after 8 years

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively
