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.
