A. What equation represents how much money Jane will have in total after saving for d days? Response area
B. What equation represents how much money Ellis will have in total after saving for d days? Response area
C. What equation would be used to find out how many days it will take for Jane and Ellis to have the same amount of money saved? Response area
D. After the amount of time found above, how much will Jane and Ellis each have saved?
A. 100 + 5d
B. 75 + 7d
C. 100 + 5d = 75 + 7d
D. Plug in the value of d from the equation above into either Jane or Ellis's equation to find the amount saved.
D: options: ($275, $162.50, $15, $325.50, or $175.)
is this correct?
$175
To find the amount Jane and Ellis will each have saved after equal amount of time, we can substitute d = 25 (from previous calculation) into either of the equations:
For Jane: 100 + 5(25) = $175
For Ellis: 75 + 7(25) = $175
Therefore, after 25 days, both Jane and Ellis will have $175 saved.
