The teacher assigned a minimum of 25 pages of reading for homework. Harrison read 10 more pages than assigned. Pam read 15 more pages than Harrison and Sam read twice the amount of Pam. How many pages did Sam read? Think carefully first, then make a decision:
Harrison read 10 more than the assigned 25 pages so he read 10 + 25 = 35 pages. Pam read 15 more pages than Harrison's 35 pages so she read 15 + 35 = 50 pages. Sam read twice the amount of Pam's 50 pages so he read 2 * 50 = 100 pages. So, the answer is 100.
