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?

$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

The cost of a book is $22.50/4 = $5.625

The cost of 2books and a person is

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

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
