Step 1: Convert the mass of the pop tabs from lbs to kg, by multiplying it by 0.453592 (1 lb = 0.453592 kg). 1267 pop tabs * 0.453592 = 575.540704 kg. Step 2: Calculate the number of pop tabs required by dividing the cost of the wheelchair by the price per kg of the pop tabs. 1500 / 0.88 = 1702.27 kg. Step 3: Multiply the number of kgs needed by the mass of one kg of pop tabs. 1702.27 * 575.540704 = 983720.7 pop tabs. Thus, 983720.7 pop tabs are needed to purchase a wheelchair worth $1500.
