The Xaoting will save $4.86
We have to find how much Xaoting will save
Therefore we need to calculate the prices of the socks without the advertised sales price.
We have given that $5.00 per pair,
Xaoting buys 3 pairs and notices that the socks do not ring up at the advertised sale price. and sales tax is 8%.
$5.00 per pair x 3 = $15
Sales tax = 8% or 0.08
What is the formula for total price?
Total price=total fixed cost+ total variable cost
Therefore,
Total price=total fixed cost+total variable cost
= (15.00 x 0.08) + 15.00
= 1.20 + 15.00
= $16.20
Total price = $16.20
Now have to find how much it would be if the socks were on the advertised price.
Advertise on sale for $3.50 per pair
So,
$3.50 x 3 = $10.50
Advertised Total price = (10.50 x 0.08) + 10.50
= 0.84 + 10.50
= $11.34
So,
To find how much Xaoting will save by subtracting the regular price to the advertised price.
Savings = $16.20 - $11.34
= $4.86
Therefore,
The Xaoting will save $4.86
