Final answer:
To find the total percent growth rate in sales from last week to this week, we calculate the percentage decrease as there was a decline in sales. The percentage decrease is 11%, indicating that there is no growth rate. Thus, the options provided do not reflect the decrease in sales.
Step-by-step explanation:
To calculate the total percent growth rate in sales, we need to compare this week's total sales to last week's. Last week, the sales were $2000 for mascara and $3000 for eyeliner, which adds up to $5000. This week, the totals are $1850 for mascara and $2600 for eyeliner, summing to $4450.
First, we determine the difference in sales between the two weeks:
Last week's sales - This week's sales = $5000 - $4450 = $550 decrease.
To find the percentage change, we use the formula:
Percentage change = (Change in quantity / Original quantity) × 100%
Substitute the values into the formula:
Percentage change = ($550 / $5000) × 100% = 11%
However, since the sales decreased, we do not have a growth rate but rather a decline. Therefore, none of the given options A) 20%, B) 25%, C) 15%, or D) 30% are correct.
