Answer: white = $13, double = $14
<u>Step-by-step explanation:</u>
Let white chocolate chip dough = x
Let double chocolate chip dough = y
Mary: 3x + 2y = 67
Darryl: <u> -(3x + 4y = 95)</u>
-2y = -28
<u> ÷-2 </u> <u>÷-2 </u>
y = 14
3x + 2y = 67
3x + 2(14) = 67
3x + 28 = 67
<u> -28 </u> <u>-28</u>
3x = 39
<u>÷3 </u> <u>÷3 </u>
x = 13
