Question

The cost of a book is $25 more than twice the cost of a geometry box. Find the cost of the book if the total cost is $130.​

Answer 1

Answer:

let the cost of geometry box be =$X

cost of book will be =$ 2X+25

we know that,

X+2X+25=130

3X+25=130

3X=105

X=35

cost of book will be 2(35)+25

=70+25

=$95
