Answer:
Step-by-step explanation:
He needs to mix 1 cup of brown sugar and 1/2 cup of granulated sugar to make each tray of 60 cookies.
The means that the ratio of the number of cups of brown sugar to the number of cups of granulated sugar is 2 : 1
Lyle uses a total of 75 cups of his sugar mixture.
Therefore, the number of cups of brown sugar used each week is
2/3 × 75 = 50 cups
the number of cups of granulated sugar used each week is
1/3 × 75 = 25 cups
Therefore, the number of trays of cookies made each week would be
50 trays
The number of cookies made each week would be
50 × 60 = 3000 cookies
