The total cost of the stools is $540.
<h3>The system of equations that can be used to represent the question</h3>
a + b = 32 equation 1
3a + 4a = 108 equation 2
Where:
a = three legged stools
b = four legged stools
<h3>What is the number of three legged stools bought? </h3>
In order to determine the required value, take the following steps:
Multiply equation 1 by 3
3a + 3b = 96 equation 3
Subtract equation 3 from equation 2
b = 12
<h3>What is the number of three legged stools bought? </h3>
Substitute for b in equation 1
a + 12 = 32
a = 32 - 12
a = 20
<h3>What is the total cost of the stools?</h3>
20(15) + 20(12) =
240 + 300 = $540
