At Best Buy they have a 60" TV that sells for $1250 and is on sale for 15% off. If the sales tax is 6.5%, what is the final cost
NNADVOKAT [17]

Answer:

Step-by-step explanation:

The sale price = Initial Cost - 15% of the initial Cost

The sale price = 1250 - 15/100 * 1250

The sale price = 1250 - 187.5

The Sale Price = 1062.5

Now you add on the sales tax

Cost with Sales Tax = 1062.50 + 6.5/100 * 1063

Cost with Sales Tax = 1062.50 + 69.06

Cost with Sales Tax = 1131.56 dollars.

£14.50 increased by 7%
Kryger [21]
My way is 14.50/100 to give you one percent. So one percent is .145 mutiply that by 7 to give you 1.02 so 14.50+1.02=15.52. So 15.52 is the answer.
