At a college, the cost of tuition increased by 9%. Let b be the former cost of tuition. Use the expression b +0.09b for the new cost of tuition. Write an equivalent expression by combining like terms. What does your equivalent expression tell you about how to find the new cost of tuition? Choose the correct answer below. O A. 0.91b; multiply the former cost by 0.91. COB. 0.91; add 0.91% of the new cost to the former cost. OC. 0.09: add 0.09% of the former cost to the new cost. OD. 1.09b; multiply the former cost by 1.09.
