Answer:

Her mistake was in step 1

Step-by-step explanation:

Given the expression solved by Alanna

4c = 12

To get c, we will divide both sides of the equation by 4:

4c/4 = 12/4

c = 12/4

c = 3

Alanna made mistake in step 1 where she divided multiplied the right hand side of the equation by 4 instead of dividing by 4

Country carpets charge $22 per square yard for carpeting and an additional installation fee of $100. City carpets charges $25 fe
Goshia [24]
X is the number of carpeting done
22x+100=25x+70
22x=25x+70-100
22x=25x-30
22x-25x=-30
-3x=-30
x=-30/-3
x=10

A person would have to do the carpeting 10 times in order to pay the same price for both companies (equal).
I dont know if that's your question but this is what is usually asked when giving a problem of that kind.
