$12.083

Step-by-step explanation:

The cost of 3 pencils is $ 2.50

The cost of 4 books is $22.50

The cost of a person is $2.50/3 = $0.83333

2*$5.625+$0.8333

$12.083

pencil= $0.83 books=$11.25

Step-by-step 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
