Abel and Babel are Shaun’s classmates. They wanted to write an equation to represent the relationship between the number of miles Shaun ran and the minutes it took him. They came up withthe following equation:
y=15x
Explain why this equation is incorrect using calculations/evidence.

Katie and Margarita have $20.00 each to spend at Students' Choice book store, where all students receive a 20% discount. They both want to purchase a copy of the same book which normally sells for $22.50 plus 10% sales tax.
- To check if she has enough to purchase the book, Katie takes 20% of $22.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount.
- Margarita takes 80% of the normal purchase price and then computes 110% of the reduced price.
