PEMDAS ( ), Exponents, Multiplication, Division, Addition, Subtraction so first we will do (23+10x9) = 33 x 9 =297 then you do division so 50/10= 5 so right now you have 10+297+5 once you add that you should have 312 as your answer. If you don't follow the PEMDAS rule you will get 128 for your answer.
My answer: 375 pages Reasoning: Well if it took 20mins to print 250 pages then divide both in half. 10mins to print out 125 pages. Then multiply both by 3. 30mins to print out 375 pages
