Answer: 60
Step-by-step explanation:
Given
The ratio of chocolate chip to sugar cookies is 5:2
If she bakes 210 cookies in one day
Suppose she baked x amount of chocolate chips on that day
So, we can write
[tex]\Rightarrow x=\dfrac{2}{5+2}\times 210\\\\\Rightarrow x=\dfrac{2}{7}\times 210=60[/tex]
There were 60 sugar cookies on that day
