Answer 1

Answer: The total cost of the desk including sales tax will be lower at store A by about $9.

Step-by-step explanation:

Hi, to answer this question we have to calculate each store price:

Total cost : desk price x(1+ tax rate in decimal form ( divided by 100))

A = 289.99 (1+7/100) = 289.99 ( 1.07) = $310.28

B = 299.99 (1+ 6.5/100) = 299.99 ( 1.065) = $319.48

Since cost B is higher, we have to subtract cost A to cost B to obtain the price difference:

319.48 -310.28 = 9.19 = about $9

So, The total cost of the desk including sales tax will be lower at store A by about $9.
