Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day.
What equation represent how much money Judy will have in total after saving ford days? _ (y=7d+100 , y=100d+75 , y=7d+75 , y=5d+100 , y=75d+7 , y=5d+75 , y=100d+5)
What equation represents how much money Elenore will have in total after saving for d days? _ (y = 100d + 75 , y = 5d + 75 , y = 100d + 5 , y = 7d + 75 , y = 7d + 100 , y = 75d + 7 , y = 5d + 100)
What equation would be used to find out how many days it will take for Judy and Elenore to have the same amount of money saved? _ ( 7d+5d=100+75 , 100d+5=75d+7 , 5d+100=7d+75 )
After the number of days it took both to have the same amount of money saved, how much money do they have each? _ ( $325 , $162.50 , $175 , $15 , $275 )
The equation that represents how much money Judy will have in total after saving for d days is y = 5d + 100.
The equation that represents how much money Elenore will have in total after saving for d days is y = 7d + 75.
To find out how many days it will take for Judy and Elenore to have the same amount of money saved, the equation would be 5d + 100 = 7d + 75.
After the number of days it took both to have the same amount of money saved, they will each have $162.50.
The equation that represents how much money Judy will have in total after saving for d days is y = 5d + 100.
The equation that represents how much money Elenore will have in total after saving for d days is y = 7d + 75.
To find out how many days it will take for Judy and Elenore to have the same amount of money saved, we can set their equations equal to each other:
5d + 100 = 7d + 75
After solving the equation, we find that it will take 12.5 days for Judy and Elenore to have the same amount of money saved.
To find out how much money they each have after that time, we can substitute the value of d into either of the original equations. Using y = 5d + 100 or y = 7d + 75, we find that both Judy and Elenore will have $162.50 saved.
To find the equation that represents how much money Judy will have in total after saving for d days, we can start with her initial amount of $100 and then add the amount she saves each day, which is $5. So the correct equation is y = 5d + 100.
To find the equation that represents how much money Elenore will have in total after saving for d days, we can start with her initial amount of $75 and then add the amount she saves each day, which is $7. So the correct equation is y = 7d + 75.
To find out how many days it will take for Judy and Elenore to have the same amount of money saved, we can set their equations equal to each other and solve for d:
5d + 100 = 7d + 75
To solve this equation, we can first subtract 5d from both sides to isolate the variable:
100 = 2d + 75
Next, we can subtract 75 from both sides to further isolate the variable:
25 = 2d
Finally, we can divide both sides by 2 to solve for d:
d = 12.5
So it will take 12.5 days for Judy and Elenore to have the same amount of money saved.
After the number of days it took for them to have the same amount saved, we can substitute this value into any of their original equations to find out how much money they each have. Let's use Judy's equation:
y = 5(12.5) + 100
y = 62.5 + 100
y = 162.5
So after 12.5 days, Judy will have $162.50 saved.
