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.
