While out shopping for new clothes, xaoting sees a sign for cozy socks advertised on sale for $3.50 per pair. the regular price of the socks is $5 per pair. xaoting buys 3 pairs and notices that the socks do not ring up at the advertised sale price, so she has the cashier do a price check. if the sales tax is 8%, how much does xaoting save by paying attention at the register? a. $3.66 b. $4.50 c. $4.86 d. $5.70

C. $4.86

Step-by-step explanation:

To find how much Xaoting will save, we first need to calculate the prices of the socks without the advertised sales price.

$5.00 per pair x 3 = $15.00

Sales tax = 8% or 0.08

Total price = (15.00 x 0.08) + 15.00

Total price = 1.20 + 15.00

Total price = $16.20

Now that we know how much the cashier had put in the register, we now have to find how much it would be if the socks were on the advertised price.

$3.50 per pair x 3 = $10.50

Sales tax = 8% or 0.08

Advertised Total price = (10.50 x 0.08) + 10.50

Advertised Total price = 0.84 + 10.50

Advertised Total price = $11.34

Now we can find how much Xaoting will save by subtracting the regular price to the advertised price.

Savings = $16.20 - $11.34

Savings = $4.86

So the answer is C. $4.86.
