Question

A video game is on sale at Amazon for 35% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $21 each. They will have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game.

Pat takes 35% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay.

Henri finds 65% of the original price and then calculates 110% of the sale price.



Will Pat's strategy calculate the correct total? Explain the calculations.

Will Henri's strategy calculate the correct total? Explain the calculations.

Do they each have enough to purchase the game?

Explain your answers using complete sentences and show your work.

Answer 1

Pat will but Henry will not

Answer 2

yes pat will, because he is taking 35% off of the original price to get the sales price. no henry wont, because the total is supposed to go down not up. no they will not be able to buy 1 for each of them because 1 game costs $18.70

Explanation:

28.50/100=0.285

0.285=0.28

0.28*35=9.80

28.50-9.80=18.70
