A company hired a printer to produce a total of x + 1 envelopes. The job consisted of two types of envelopes, 2¢ envelopes and 3¢ envelopes. If the company requested 1 more 2¢ envelopes than 3¢ envelopes, which of the following expressions denotes the cost, in cents, of the total x + 1 envelopes ?
Choices.
A) (7x-4)/2 B) 5x+7 C) 4x-1 D) (3x+22)/2 E) (9x-4)/2
We can take   X+1 = 5   X= 4   So 2c envelopes will be 3   and 3c envelopes will be 2   So total cost will be 12   Then that is our target   Plug x =4 in answer choices   Only (7x-4)/2 works   Correct (7x-4)/2nswer : (7x-4)/2
