NeTakaya

Answer:

the cost of each cookie is $\$1.25$

the cost of each muffin is $\$1.00$

Step-by-step explanation:

x-----> the cost of each cookie

y----> the cost of each muffin

we know that

$8x+3y=13$ -----> equation A

$4x+6y=11$ -----> equation B

Using a graphing tool

The solution of the system of equations is the intersection point both graphs

The intersection point is $(1.25,1)$

see the attached figure

therefore

the cost of each cookie is $\$1.25$

the cost of each muffin is $\$1.00$
