Jessica has 5 bills coming up. If the first bill is 110.65 and the following four are 174.62 how much could she pay extra on the first one to make them all equal?

Just add up them all to get the total, take the average, and then get the difference from the first bill.
(110.65 + 4*174.62)/5 - 110.65 = 51.176
So, if she adds $51.18 to the first bill, they will all be
110.65 + 51.18 = 161.83
check:
161.83 * 5 = 809.15
110.65 + 4*174.62 = 809.13
So, she'll end up paying an extra 2 cents after roundoff error.

Respond to this Question
To find out how much extra Jessica could pay on the first bill to make them all equal, we need to calculate the total amount of the four following bills and divide it by 4 to get the equal amount for each bill.
Let's calculate the total amount of the four following bills:
Total amount of the four following bills = 4 * 174.62
Next, divide the total amount by 4 to get the equal amount for each bill:
Equal amount for each bill = (4 * 174.62) / 4
Finally, subtract the original amount of the first bill from the equal amount to determine how much extra Jessica could pay to make them all equal:
Extra amount to pay on the first bill = (4 * 174.62) / 4 - 110.65
Now, let's plug in the values and calculate:
Total amount of the four bills = 4 * 174.62 = 698.48
Equal amount for each bill = 698.48 / 4 = 174.62
Extra amount to pay on the first bill = 174.62 - 110.65 = 63.97
Therefore, Jessica could pay an extra $63.97 on the first bill to make them all equal.
