Percentage Question

Question

Nate planted 80 pumpkin seeds with a germination rate of 65%. How many pumpkin seeds should he expect to germinate? My teacher skipped over teaching us this and I have no idea how to find that. 

What amount of sales will produce a commission of $221.00 if the commission rate is 6.5%? --------------------------- A football player’s rookie card decreased in value 31% over the past 20 years. This was a decrease of $67.27. What was the value of the card 20 years ago? What is the current value of the card?

Answer 1

80(0.65) = 52

 

0.065s = 221

0.065s/0.065 = 221/0.065

s = 3400

 

0.31v = 67.27

0.31v/0.31 = 67.27/0.31

v = 217

 

217 - 67.27 = 149.73 or 0.69(217) = 149.73
