1. A square classroom has 10 square yards more than 5 times the area of the hallway outside it. The classroom and hallway have a combined area that’s 50 square yards less than 10 times the area of the hallway. Find the length of each side of the classroom. (Show work to find the length of each side)

2. The area of a indigo circle is 100 square meters more than four times the area of a golden circle. If the indigo circle has an area of 1,500 square meters, what is the radius of the golden circle? (Show work to find the golden circles radius)

3. A cubed-shaped box has a volume of 343 cu. ft. What is the surface area of the box? (Show work to find the surface area of the box)

4. Whiz and Link are salesmen. If Whiz had made another $20 in sales, he would have sold three times as much as Link. Combined, they sold $80 less than 7 times Link's sales. How much money did Whiz sell? (Show work to find how much Whiz sold.)
