Josh paid for four books with three $20 bills he received $12 in change each book was the same price how much did each book cost

Three $20 bills is a total of $60

$60 - $12 = $48

He spent a total of $48 on the books

Divide the total spent by the number of books:

48 / 3 = 16

Each book cost $16

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
