How do you calculate the total amount of tax

the answer is in the first quadrant, which make the y-int positive.

i hope it is right.

do you have a picture of the table

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
