B. What equation represents how much money Ellis will have in total after saving for d
days?
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?
D. After the amount of time found above, how much will Jane and Ellis each have
saved?
A. Jane's total money after d days = $100 + $5d
B. Ellis's total money after d days = $75 + $7d
C. $100 + $5d = $75 + $7d
D. Solve for d:
$100 + $5d = $75 + $7d
$25 = $2d
d = 12.5
After 12.5 days, Jane will have $162.50 saved ($100 + $5*12.5) and Ellis will have $162.50 saved ($75 + $7*12.5).
