country carpets charges $22 per square yard for carpet and an additional installation fee of $100 city carpets charges $25 per square yard for the same carpeting
Answers
Solution :
Let 'x' be the number of carpeting done.
From the above question, the equation that we get:
Solving,
22x + 100 = 25x
22x = 25x - 100
22x - 25x = -100
-3x = -100
x = -100 / -3
x = 33.33
Therefore,
A person would have to do the carpeting 33.33 times in order to pay the same price for both companies.
Step-by-step explanation:
Let x be the number of square yards of carpeting for which the total cost charged by the two companies will be the same.
We have an expression for the total cost of Country Carpets:
($22/ 1 yd^2)* (x yd^2) + $100
= $22*x+ $100
or 22x+ 100
We also have another expression for the total cost of City Carpets:
($25/ 1 yd^2)* (x yd^2)+ $70
= $25*x+ $70
or 25x+ 70
Now set the two expressions to be equal:
22x+ 100= 25x+ 70
⇒ 100- 70= 25x -22x
⇒ 30= 3x
⇒ 30/3= x
⇒ 10= x
