Final answer:
To calculate the percent decrease in Destiny's weekly wage, subtract the new wage from the original wage, divide the result by the original wage, and multiply by 100%. The calculation shows a 30% decrease in Destiny's weekly wage from $246 to $172.20.
Step-by-step explanation:
The question relates to the concept of percent decrease in Mathematics, specifically when dealing with changes in wages or prices. To calculate the percent decrease Destiny experienced in her weekly wage, we use the formula:
Percent Change Formula
Percentage change = (Change in quantity / Original quantity) × 100%
In Destiny's case, the original weekly wage was $246, and it decreased to $172.20. The change in quantity is $246 - $172.20, which equals $73.80. Thus, the percent decrease in her weekly wage is:
Percent decrease = ($73.80 / $246) × 100% = 0.3 × 100% = 30%
The percent decrease in Destiny's weekly wage is therefore 30%, indicating a significant drop in her income. This calculation is crucial for understanding the impact of wage changes on personal finances, and it is analogous to calculating percentage increases in costs or salaries as shown in the examples provided.
