Question #4442

Sam paid $64 for 5 similar files and 3 similar textbooks.A textbook cost $8 more than a file.What was the cost of one textbook?

Expert's answer

let file cost x$ then textbook cost (x+8)$ so we can write equation

5*x+3*(x+8)=64 5x+3x+24=64 8x=40 x=5$.

so one file cost 5$.

and one

textbook cost 5+8=13$

5*x+3*(x+8)=64 5x+3x+24=64 8x=40 x=5$.

so one file cost 5$.

and one

textbook cost 5+8=13$
