lozanna [386]

Answer: Jenna sold 280 and Becca sold 105 boxes.

Step-by-step explanation:

Let 3x be the number of cookies Becca sold.

Then, the number of cookies Jenna sold = 8x

Since Combined, they sold a total of 385 boxes of cookies.

So, $3x+8x=385$

$\Rightarrow\ 11x=385\\\\\Rightarrow\ x=\dfrac{385}{11}\\\\\Rightarrow\ x=35$

So, Jenna sold 8(35) = 280 boxes

and Becca sold 3(35)= 105 boxes

Hence, Jenna sold 280 and Becca sold 105 boxes.
