Answer:
50 trays
3000 cookies
Step-by-step explanation:
We are given the following in the question:
1 cup of brown sugar and [tex]\frac{1}{2}[/tex] cup of granulated sugar makes a tray of 60 cookies.
Total cups of sugar used(brown and granulated) = 1.5 cups
Number of sugar cups used by Lyle each week = 75
We have to find the number of trays made each week.
[tex]\text{Ratio} = \dfrac{\text{Cups of sugar mixture}}{\text{Number of trays}}\\\\\dfrac{1.5}{1} = \dfrac{75}{\text{Number of trays}}\\\\\Rightarrow \text{Number of trays} = \dfrac{75}{1.5} = 50[/tex]
Thus, 50 trays of cookies are made each week.
Total number of cookies made each week =
[tex]=\text{Number of trays}\times \text{Number of cookies in 1 tray}\\=50\times 60\\=3000[/tex]
Thus, 3000 cookies are made each week.
