Tammy bought 3 pounds of coffee.

Solución

To find out how many pounds of coffee Tammy bought, we can set up an equation based on the information given: Let \( x \) be the number of pounds of coffee Tammy bought. The total cost of the coffee is \( 8.79x \) dollars. Tammy had \( \$ 90 \) on her gift card initially and had \( \$ 63.63 \) left after buying the coffee. So, the amount she spent on coffee is \( 90 - 63.63 = 26.37 \) dollars. Therefore, we can set up the equation: \[ 8.79x = 26.37 \] Now, we can solve for \( x \) to find out how many pounds of coffee Tammy bought. Solve the equation by following steps: - step0: Solve for \(x\): \(8.79x=26.37\) - step1: Divide both sides: \(\frac{8.79x}{8.79}=\frac{26.37}{8.79}\) - step2: Divide the numbers: \(x=3\)

Beyond the Answer

Tammy initially had \( \$ 90 \) on her gift card. After purchasing coffee, she had \( \$ 63.63 \) left. To find out how much she spent, we subtract the remaining amount from the initial amount: \[ 90 - 63.63 = 26.37 \] Now, to find out how many pounds of coffee she bought, we divide the amount spent by the cost per pound: \[ \frac{26.37}{8.79} \approx 3 \] So, Tammy bought approximately \( 3 \) pounds of coffee! Isn't it amazing how a simple addition and division can solve such a real-life scenario? Buying coffee on a gift card is a practical way to enjoy your favorite brews without breaking the bank! And, hey, making sure you keep track of your gift card balance before splurging can save you from any surprises down the line!
