At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account
at the end of the school year. Each week, she withdraws $30 for spending money. To determine how many weeks she can spend $30, Jamie wrote and solved this inequality. 500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10 Review Jamie's work. What was her error? Jamie should have used the less than or equal to sign when writing the inequality. Jamie should have reversed the inequality when using the division property of inequality. Jamie should have added 500 to both sides. Jamie should have started by dividing by –30.
Let the total amount of pages be t t=30+1/8t+2/8t now simplify t=30+3/8t 5/8t=30 divide 30 by 5 1/8=6 now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
