Judy has $100 and Elenore has $75. Judy is saving $5 per day and Elenore is saving $7 per day. (4 points)
What equation represents how much money Elenore will have in total after saving for d days?
The equation that represents how much money Elenore will have in total after saving for d days is:
Elenore's total savings = $75 + ($7*d)
This equation accounts for the initial $75 that Elenore has, and then adds $7 for each day she saves (which is represented by d days).
The equation that represents how much money Elenore will have in total after saving for d days can be written as:
Elenore's total savings = $75 + ($7 per day) x (number of days, d)
In equation form, it would be:
Elenore's total savings = 75 + 7d
To determine the equation that represents how much money Elenore will have in total after saving for d days, we need to take into consideration that Elenore saves $7 per day.
Let's break it down step by step:
- Elenore saves $7 per day.
- After 1 day, Elenore will have saved $7.
- After 2 days, Elenore will have saved $7 * 2 = $14.
- After 3 days, Elenore will have saved $7 * 3 = $21.
From this pattern, we can see that for each day Elenore saves, her savings increase by $7.
Therefore, the equation that represents how much money Elenore will have in total after saving for d days is:
Total savings = $7 * d
In this case, since we want to represent Elenore's total savings after d days, the equation is:
Total savings = 7d
