Enrique is saving money to buy a graphing calculator. So far he has saved $30. His math teacher told him he has saved 40% of what he will need. How much does the calculator cost? I know the answer, I just need the steps. Thanks! :)

The calculator cost $75

Step-by-step explanation:

Let

x ----> the calculator cost

Remember that

we know that

The cost of the calculator multiplied by the percentage saved must be equal to the amount saved by Enrique

so

solve for x

Divide by 0.40 both sides

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
