Let's call the number of days it takes for Andre and Erin to have the same amount of money "x".
After x days, Andre will have saved a total of:
$30 + ($5/day * x)
After x days, Erin will have saved a total of:
$14 + ($9/day * x)
We want to find the value of x that makes these two expressions equal:
$30 + ($5/day * x) = $14 + ($9/day * x)
We can start solving for x by subtracting $14 and $5/day from both sides:
$16 = ($4/day * x)
Now we can solve for x by dividing both sides by $4/day:
x = 4 * $16/day
x = 64/4
x = 16
Therefore, it will take 16 days for Andre and Erin to have the same amount of money.
After x days, Andre will have saved a total of:
$30 + ($5/day * x)
After x days, Erin will have saved a total of:
$14 + ($9/day * x)
We want to find the value of x that makes these two expressions equal:
$30 + ($5/day * x) = $14 + ($9/day * x)
We can start solving for x by subtracting $14 and $5/day from both sides:
$16 = ($4/day * x)
Now we can solve for x by dividing both sides by $4/day:
x = 4 * $16/day
x = 64/4
x = 16
Therefore, it will take 16 days for Andre and Erin to have the same amount of money.
