LWH=V

increasse by 10% means times 1.10
increase by 20% is times 1.20



L turns to 1.1L
W turns to 1.1W
H turns to 1.2H

(1.1L)(1.1W)(1.2H)=1.452LWH
so it is increased by 45.2%

Waylon is back-to-school shopping with his mom at a large department
levacccp [35]

Answer:

Waylon's Purchase will cost $198.05, and section B depends.

Explanation: Section A is 85% of 233 since thats the total, making the answer to section A $198.05. The answer to section B depends because if he wants more school supplies, then yes, he would want to buy more things for better deals. But if he’s on a budget, then he wouldn't want to spend as much money since saving 20% on something over $300 is more than saving 15% on something over $200.
