Leslie bought '3' identical phone cases for a total cost of $20.97
including a $6.99 flat rate fee for shipping.
'c' the cost of the cell phone case
What equation 'could be used' to find the cost for each cell phone case, c?
3c + 6.99 = 20.97 ****
A. is Your Answer
Then... one could solve for 'c'
c = (20.97 - 6.99)/3
Answer by math_tutor2020(3817) (Show Source): You can put this solution on YOUR website!
c = cost of one phone case
3c = cost of three phone cases
3c+6.99 = total cost after adding on shipping
3c+6.99 = 20.97 is the equation to set up.
