Answer:

Maria made 248 cookies, Denise made 62 cookies, Joseph made 372 cookies.

Step-by-step explanation:

Number of cookies made by Maria is m,

made by Denise is d,

made by Joseph is j

We can write the following equations from the word:

m = 4d

j = 6d

m + d + j = 682

We can substitute both 1st and 2nd equation in 3rd and solve for d:

m + d + j = 682

4d + d + 6d = 682

11d = 682

d = 62

Thus,

m = 4(62) = 248

and

j = 6(62) = 372

Maria made 248 cookies, Denise made 62 cookies, Joseph made 372 cookies.
