Question

Jo participated in a read-a-thon to raise money for a local library. She raised $20 plus $1.50 per book that she red. She raised a total of $59. Let X represent the number of books Jo read. In the first blank, write an equation that can be used yo determine the number of books Jo read. In the second blank, answer how many books did she read?

Answer 1

Multiply 1.50 by x ( number of books read and add it to the 20:

Equation: y = 20 + 1.50x

Replace y with the amount she raised and solve for x:

59 = 20 + 1.50x

Subtract 20 from both sides:

39 = 1.50x

Divide both sides by 1.50:

x = 39 /1.50 = 26 books were read.
