Smiley's Cookies makes the best chocolate chip cookies in town! Yesterday, the store sold 7 large cookies for every 5 small cook

True [87]

Answer: The number of small cookies sold = 75

Step-by-step explanation:

GIven: Yesterday, the store sold 7 large cookies for every 5 small cookies.

Let 7x be the number of cookies and 5x be the number of small cookies. (i)

They sold 30 more large cookies than small cookies.

i.e. $7x-5x=30$ (Using (i))

$\Rightarrow\ 2x=30\\\\\Rightarrow\ x=\dfrac{30}{2}\\\\\Rightarrow\ x=15$

Thus, the number of small cookies sold = 5 (15)=75 (Using (i))

Hence, the number of small cookies sold = 75
