A tailor orders black thread by the case. A case of 150 spools of black thread costs $40.00. In one week, the tailor uses 1/2 of the case of black thread. Which method could be used to find the amount of money the tailor spends on black thread in 3 weeks?






1/2 × $40.00 × 3





(1/2 ÷ $40.00) × 3





($40.00 ÷ 150) × 1/2 × 3





150 ÷ $40.00 × 1/2 × 3
