The previous balance on Hector Todd's savings account is $618.21. He has $4.31 in interest, $466.26 in deposits, and $10.10 in withdrawals. What is his new balance?
$1,068.78
$1,078.68
O $1,178.68
$1,078.90

$1,078.68

Step-by-step explanation:

Here, we want to calculate the balance

That would be adding interest plus deposit plus balance minus withdrawals

That would be;

618.21 + 466.26 + 4.31 - 10.10 = $1,078.68

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
