Answer: Her total before tax is $57.56.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
First we have to sum the prices:
$62.50 + ($4.75 x3) = $76.75 (total without discount)
To calculate the discount we have to multiply the total by 0.25 (25/100 = 0.25 decimal form).
Mathematically speaking:
$76.75 x 0.25 =$19.18
And finally we subtract the value calculated to the total without discount:
$76.75 - $19.18 = $ 57.56
Her total before tax is $57.56.
