Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.
<span><span> </span><span>Steps:<span>Divide the decimal number by 16. Treat the division as an integer division. Write down the remainder (in hexadecimal).Divide the result again by 16. Treat the division as an integer division. Repeat step 2 and 3 until result is 0.<span>The hex value is the digit sequence of the remainders from the last to first.</span></span></span></span>

Subtract 10 from both sides.

Since the square of a number, x, equals a negative number, -1, the answer cannot be a real number because the square of a real number is always non-negative. Therefore, there is no real number solution to this equation.
Answer: <span>B. no real number solutions</span>
