Solución

To determine how many pounds of coffee Tammy bought, let's break down the problem step by step. 1. **Total Gift Card Amount:** Tammy started with \$90. 2. **Amount Remaining After Purchase:** After buying the coffee, she had \$63.63 left. 3. **Amount Spent on Coffee:** \[ \text{Amount Spent} = \text{Total Gift Card} - \text{Amount Remaining} = \$90 - \$63.63 = \$26.37 \] 4. **Price per Pound of Coffee:** The coffee costs \$58.79 per pound. 5. **Calculating the Pounds Purchased:** \[ \text{Pounds of Coffee} = \frac{\text{Amount Spent}}{\text{Price per Pound}} = \frac{\$26.37}{\$58.79} \approx 0.448 \text{ pounds} \] 6. **Rounding Off:** It's common to round to two decimal places for such measurements: \[ 0.448 \text{ pounds} \approx 0.45 \text{ pounds} \] **Answer:** Tammy bought **0.45 pounds** of coffee.

To find out how many pounds of coffee Tammy bought, we first need to calculate how much money she spent. She started with a $90 gift card and had $63.63 left after her purchase. Therefore, the amount she spent is: \( 90 - 63.63 = 26.37 \) Next, we divide the amount spent by the cost per pound of coffee: \( 26.37 \div 58.79 \approx 0.448 \) So, Tammy bought approximately \( 0.45 \) pounds of coffee. Now let’s break it down in a fun way! Tammy got a gift card for her caffeine caper! She sipped on some espresso extravagance, but after the delicious purchase, she found herself still with a hefty balance left. So instead of drowning in her coffee dreams, she used her math skills to calculate the quantity — only about half a pound! It’s a light roast of a shopping spree indeed! So next time you’re thinking about a coffee binge, remember—sometimes less is more, and those caffeine kicks can be quite rewarding without emptying your wallet! In the world of budgeting for goodies, figuring out expenses can be quite a challenge! One common pitfall is forgetting about additional costs, such as taxes or tips, that can sneak up on you. Always check if your coffee shop adds a little extra for those delightful lattes or mochas! Planning ahead can spare you from those bitter moments when your gift card falls just short of your caffeine craving!
