Answer 1

To calculate how much William made this year after making 340% more than last year, you first need to find out what 340% of last year's earnings ($620) is.

1. Calculate 340% of $620: \[ 340% \text{ of } 620 = \frac{340}{100} \times 620 = 3.4 \times 620 = 2108 \]

2. Now, add that amount to last year's earnings to find out how much William made this year: \[ \text{Total this year} = 620 + 2108 = 2728 \]

Therefore, William made $2728 this year.
