Here is the step by step explaination
Tax = 0.35 * Earnings (Earnings < $100,000)
Tax = 0.35 * $100,000 + 0.45 * (Earnings - $100,000) ($100,000 < Earnings < $500,000)
Tax = 0.35 * $100,000 + 0.45 * $400,000 + 0.55 * (Earnings - $500,000)
(Earnings > $500,000)
8 pieces of wood. It takes 6 inches to make 1 dowel, so with 4 feet (48 inches) you could make 8 dowels per board. You would need 7.5 boards to make 60, but you cant buy half a board, so the answer is 8
3+4+1 for each class so it's 8
8 x 6 for all the classrooms so it's 48. The school buys 48 games
-2(6-x)= 3x, the solution is find the value of x, you must apply distributive property, tho the first term, -12+2x= 3x⇒ 3x-2x= -12⇒ x = -12, the answer correct is option D
