Mary purchases four book online. the book were the same price each, and the shipping fee was $7.25. if the total cost was $55.25, what was the price of each book?

The price per book that Mary purchased is $12

Step-by-step explanation:

Mary's total cost can be expressed as;

C=(p×n)+s

where;

C=total cost

p=price per unit of books

n=number of books purchased

s=shipping fee

In our case;

C=$55.25

p=unknown

n=4

s=$7.25

replacing;

55.25=(4×p)+7.25

4 p+7.25=55.25

4 p=55.25-7.25

4 p=48

p=48/4

p=12

The price per book that Mary purchased is $12

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

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
