Answer 1

Nam,

 

1) This is just the equation to be used for solving, so there is no question being asked.

 

2) Cost for Clara is $37.10. So sale price is p = c/1.06 = 37.10/1.06 = $35

 

3) Cost for Manuel is $10.59, Sale price = 10.59/1.06 = $9.99

 

4) Cost for parents is $165.84, Sales price = 165.84/1.06 = $156.45

 

Sales tax = 165.84 - 156.85 = $9.39
