After a 20% discount and 5% sales tax, a book costs $16.80. What was the original price of the book?

19.15

Step-by-step explanation:

16.80 x 5% = 0.84

16.80 - 0.84 = 15.96

15.96 x 20% = 3.19

15.96 + 3.19 = 19.15

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
