Question

A video game is on sale at Amazon for 15% off the original price of $24.50. Both Pat and Henri want to purchase the game, but they only have $21 each. They each 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 15% of $24.50 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 85% 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's answer
$24.50*0.15=3.675 --> $3.68
$24.50-$3.68=$20.82
$20.82*0.10=$2.082 --> $2.09
$20.82+2.08=$22.91

Henri's answer
$24.50*0.85= $20.825 --> $20.83
$20.83*1.1=$22.9075 --> $22.91

Pat and Henri's answers will both calculate the correct total and since the total amount of dollars is greater than the amount they have $21 will not be enough for both of them to purchase 2 games (one for each of themselves), so they do not have enough money for each of them to purchase the game.
