Step-by-step explanation:
Sean is buying 9/16 pounds of tea, and you want to write the amount of tea as a decimal. To convert the fraction 9/16 to a decimal, you divide the numerator by the denominator. Doing the division, 9 ÷ 16 = 0.5625. So, Sean is buying 0.5625 pounds of tea. Since the cost is $24 per pound, you would then calculate the total cost by multiplying the amount in pounds by the cost per pound, which is 0.5625 × $24. This equals $13.50.
