Your friend makes a comment about how expensive the baseball card pack was that he purchased. He says 10 years ago he could buy a pack of baseball cards for \( \$ 5 \). Assuming inflation is \( 3 \% \), compounded continuously, how much did he pay for the pack today? Round your answer to the nearest cent (hundredth).

To find out how much your friend paid for the pack today considering 10 years of continuous inflation at a rate of 3%, we can use the formula for continuous compounding: \[ A = Pe^{rt} \] where - \( A \) is the amount of money accumulated after time \( t \), - \( P \) is the principal amount (the initial amount of money, which is \( \$ 5 \)), - \( r \) is the rate of interest (inflation rate, which is 0.03), - \( t \) is the time the money is invested or borrowed for (10 years), - \( e \) is Euler's number (approximately 2.71828). Now, let's plug in the values: \[ A = 5e^{0.03 \times 10} \] \[ A = 5e^{0.3} \] Calculating \( e^{0.3} \) gives approximately \( 1.34986 \). Now, calculate \( A \): \[ A = 5 \times 1.34986 \approx 6.7493 \] Rounding to the nearest cent, he paid approximately \( \$ 6.75 \) for the baseball card pack today.
