Rowan has $50 in a savings jar and is putting in $5 every week. jonah has $10 in his own jar and is putting in $15 every week. each of them plots his progress on a graph with time on the horizontal axis and amount in the jar on the vertical axis. which statement about their graphs is true?
(1) rowan's graph has a steeper slope than jonah's.(2) rowan's graph always lies above jonah's.(3) jonah's graph has a steeper slope than rowan's.(4) jonah's graph always lies above rowan's.

(3) Jonah's graph has a steeper slope than Rowan's

Step-by-step explanation:

First we are going to write the equations for the amount of money that each one save

y = a+bx

 Where y: Amount of money in the jar

             a: Initial saving

             b: Money saved every week ( graph's slope )

             x: Number of week

Then, for Rowan

y = 50 + 5x

and for Jonah

y = 10 + 15x

Initially Rowan's graph lies above Jonah's graph but this situation change with time.

It is always true that Jonah's graph has a steeper slope than Rowan's, because for Rowan's graph the slope is 5 and for Jonah's graph the slope is 15

Then the answer is:  

(3) Jonah's graph has a steeper slope than Rowan's

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.
