Question

lucy brought 4 of her scarves to a second - hand store to sell. she was paid the same amount of cash for each scarf. before she left, lucy spent $10.50 of her earnings on a used sweater. she had $7.50 remaining. what was the value of each scarf?

Explanation:

Step1: Calculate total earnings

First, find out how much Lucy earned in total before buying the sweater. The money she spent on the sweater plus the money she had remaining is her total earnings. So, $10.50 + 7.50=18$ dollars.

Step2: Calculate value per scarf

She sold 4 scarves and earned 18 dollars in total. To find the value of each scarf, divide the total earnings by the number of scarves. So, $18\div4 = 4.5$ dollars.

Answer:

$4.5$
