Final answer:
The total cost after the discount and tax is $55.34.
Step-by-step explanation:
Frodo goes to New Army and buys two pairs of jeans for $19.99 each, 3 shirts at $7.99 each, and a pack of socks for $5. He has a coupon for 25% off his entire purchase. Sales tax is 7%.
To find the total cost after the discount and tax, we first need to calculate the cost of the items before any discounts or taxes are applied.
The cost of two pairs of jeans is 2 x $19.99 = $39.98.
The cost of 3 shirts is 3 x $7.99 = $23.97.
The cost of the pack of socks is $5.
The total cost before any discounts or taxes are applied is $39.98 + $23.97 + $5 = $68.95.
Next, we calculate the discount. To find 25% of $68.95, we multiply 0.25 x $68.95 = $17.23.
Now, we subtract the discount from the total cost to find the discounted price: $68.95 - $17.23 = $51.72.
Finally, we calculate the sales tax. To find 7% of $51.72, we multiply 0.07 x $51.72 = $3.62.
The total cost after the discount and tax is $51.72 + $3.62 = $55.34.
