Answer:
43 shirts
Step-by-step explanation:
$660- $15 = $645, the amount spent on shirts.
$645/15= 43
The total number of shirts ordered by the student council is 43.
What is linear equation in one variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
Let the total number of shirt ordered by the student council be x.
According to the given question.
Cost of one shirt when the count of shirts are less than 25 is $20.
And, the shipping and handling charge when the count of shirts are less than 25 is $20.
Also,
Cost of one shirt when the count of shirts are more than 25 is $15.
And, the shipping and handling charge when the count of shirts are more than 25 is $15.
Since,
Total amount of money spent on shirts is $660
⇒ More than 25 shirts are ordered
Therefor, for the given scenario we have a linear equation in one variable.
[tex]15x +$15 = 660[/tex]
Solve the above linear equation in one variable.
[tex]15x + 15 = 660[/tex]
⇒ [tex]x + 1= \frac{660}{15}[/tex]
⇒ [tex]x + 1 = 44[/tex]
⇒ [tex]x = 44-1[/tex]
⇒ [tex]x = 43[/tex]
Therefore, total 43 shirts, the student council ordered.
