Question

Algebra 1 Grade 9

Could anyone please help me answer this Algebra 1 math question?

Lisa read 2/5 of her book report book over the weekend. Monday, she read 32 more pages. If she has read 310 pages total, how many pages does the book have?

Answer 1

p = total # of pages

2/5p + 32 = 310 (She read 2/5 of the book, read an addition of 32 pages, and she read a total of 310 pages.) Subtract 32 on both sides

2/5p = 278 (multiply each side by 5/2 to get p by itself)

p = 695
