enrique plans to sell his car and places a 6-line ad. his paper charges $42 for the first two lines and $6.75 per extra line, to run the ad for one week. What will enrique’s ad cost to run for three weeks

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
