Question

Shu Yi can't resist a sale. She recently bought a dress for $93 after it had been discounted 25%. She also purchased shoes that had been marked down 15%. She paid $119 for the shoes. When she got home, she told her best friend that she had saved some money. How much money did she save by purchasing the dress and shoes?

Answer 1

First divide 93 by 3 to get 25% of the original price: 31. Then multiply it by 4 to get the whole original price, which is $124. Now onto the shoes. 
Divide 119 by 17 to get 7, which is 5% of the original price for the shoes. Then multiply 7 by 20, which is $140 for shoes. 
Subtract 124-93 to get 31, the savings on the dress and also subtract 
140-119 to get 21, savings on the shoes. Then add them together to get a grand savings total of $52 in savings. Hope this helps!
