<u>Answer:</u>
y = 94.5 cups
<u>Step-by-step explanation:</u>
Let's say:
- y = oats
- x = chocolate chips = 212
=> Full Recipe = 212 + y
=> 2(Full Recipe) = 2(212 + y) = 613 cups
=> 2(Full Recipe) = 424 + 2y = 613 cups
=> 2y = 613 - 424
=> 2y = 189
=> y = 94.5
Therefore, the required oats to do double the recipe is 94.5 cups.
