First, imagine that if there were 100 students in the science club in total, there would be 40 students who want to buy the T-shirt. That's what the number 40% tells us. 65 students in total* ( 40 students buying T-shirts/ 100 students in total)= 26 students buying T-shirts. Note that students in total (in 65 students in total) and students in total (in 100 students in total) cancel out, and each student only buys one T-shirt. Thus the final answer is D. 26 Hope this would help :))
Divide the price by the number of months to find the monthly rate. <span>$237.36 ÷ 24 = $9.89 per month </span> <span>$184.50</span><span> ÷ 18 = $10.25 per month
