Question

the cost of 3 pencils is $2.50.The cost of 4 books is $22.50.What is the cost of 2 books and a pencil?​

Answer 1

pencil= $0.83 books=$11.25

Explanation:

to find the price of the pencils you have to divide the total amount by the number of pencils

$2.50/3 = $0.83 this gives you the price of one pencil

and the same for the books but multiply by the new amount of books "2"

2($22.50/4)

2($5.62)

$11.25

if you add both prices

$11.25+$0.83= $12.08

Answer 2

Answer: $12.083
