A pair of shoes usually sells for $57. If the shoes are 30% off, and sales tax is 5%, what is the total price of the shoes, including tax? $38.90 $41.90 $42.75 $42.29

OpenStudy (jhannybean):

@sammixboo @Jhannybean This questions are actually between Sam and Alex, I notice.

sammixboo (sammixboo):

OpenStudy (anonymous):

@sammixboo It's kinda a medal hunt.

OpenStudy (jhannybean):

This user seems like they are trying to find answers rather than work out the problem.

OpenStudy (anonymous):

57*0.3 then the answer multiply it by 1.05 the tax

sammixboo (sammixboo):

But anyways, to find the price after the discount you must solve this expression 57 - (57*30%) \(\rightarrow\) 57 - (57*0.3)

OpenStudy (anonymous):

OpenStudy (anonymous):

57 = 100; 0.57 = 1 39.9 = 70 (30% off) 2.75 = 5 (sales tax) 39.9+2.75=42.65

OpenStudy (alexandervonhumboldt2):

taxes increases the cost from the base(net) price.
