(1)) What is the percent of decrease from 100 to 73 ? Write your answer using a percent sign (\%).

To find the percent of decrease from 100 to 73, you can use the formula: \[ \text{Percent Decrease} = \frac{\text{Old Value} - \text{New Value}}{\text{Old Value}} \times 100 \] Plugging in the values: \[ \text{Percent Decrease} = \frac{100 - 73}{100} \times 100 = \frac{27}{100} \times 100 = 27\% \] So, the percent of decrease from 100 to 73 is **27%**. Now, if you’re ever in this situation again, a handy tip is to always subtract the new value from the old one first, then divide by the old value before multiplying by 100. It's like a mini-math workout! And remember, simple mistakes often come from forgetting to convert to a percentage, so double-check your steps to avoid any slip-ups.
