Shane and Kelvin are going to spend $11 at Popeyes where all customers are receiving a special day 15 % discount. They want to purchase a sandwich combo which sells for $11.75 plus 12% sales tax. • To see if $11 is enough to purchase the meal, Shane takes 15% of $11.75 and subtracts that amount from the normal price. He takes 12% of the discounted price and adds it back to find the purchase amount. To see if $11 is enough to purchase the meal, Kelvin takes 85% of the original purchase price and then computes 112% of the reduced price. Is Shane's approach correct or is Kelvin's approach correct? Explain how you know. ​
