Maria started a bank account in March.
The amount of money that she had in April was $4600. The amount of money she had is May was $5125. The amount of money she had in June was 5175. Write an equation where x represents the number of months while y represents the total money saved in her bank account.
well, it is not linear, since balance increased by 525, then 50
One model (quadratic) is
y = -237.5x^2 + 762.5x + 4600
I suspect a typo
To write an equation that represents the relationship between the number of months and the total money saved in Maria's bank account, we need to first identify the pattern. From the information provided, we can see that her savings increased by $25 each month.
Let's break down the information given:
In March (month 0), the amount of money saved (y) is unknown.
In April (month 1), y = $4600.
In May (month 2), y = $5125.
In June (month 3), y = $5175.
We can observe that the amount of money saved (y) increases by $25 each month. So, we can set up the equation as follows:
y = mx + b
Here, m represents the rate of change (which is $25), x represents the number of months, and b represents the initial amount of money in the account in March.
Now, we know that in March (month 0), the total money saved is unknown (represented by y). So, we need to determine the initial amount of money saved (b).
Since Maria started her bank account in March (month 0), the initial amount of money saved (b) would be the amount in April (month 1), which is $4600.
Thus, the equation that represents the relationship between the number of months and the total money saved in Maria's bank account is:
y = 25x + 4600
