$3.2

Step-by-step explanation:

Let x be the cost of each cupcake and y be the cost of each slice of pie.

We have been given that the cost of one cupcake and two slices of pie is $12.40. We can represent this information as:

We have been given that the cost of two cupcakes and three slices of pie is $20.20. We can represent this information as:

We will use substitution method to solve for the cost of one cupcake.

From equation (1) we will get,  

Substituting this value in equation (2) we will get,

Therefore, cost of one cupcake is $3.2.

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
