Equation for Jane's savings after d days: 50 + 4d
Equation for Ellis's savings after d days: 24 + 6d
Equation to find out when Jane and Ellis have the same amount saved: 50 + 4d = 24 + 6d
To solve for d:
50 + 4d = 24 + 6d
Subtract 24 from both sides:
26 + 4d = 6d
Subtract 4d from both sides:
26 = 2d
Divide both sides by 2:
d = 13
After 13 days, Jane will have saved $102 (50 + (4*13)) and Ellis will have saved $102 (24 + (6*13)).
Jane has $50 and Ellis has $24. Jane is saving $4 per day and Ellis is saving $6 per day.
What equation represents how much money Jane will have in total after saving for d days?
What equation represents how much money Ellis will have in total after saving for d days?
What equation would be used to find out how many it will take for Jane and Ellis to have the same amount of money saved?
After the amount of time found above, how much will Jane and Ellis each have saved?
