Nora and eli are making homemade spring rolls for a party. nora can make 8 spring rolls in 10 minutes. eli can make 10 spring rolls in 12 minutes. if they each make 40 spring rolls, who will finish first? can someone answer this for me , it's 12 am and i have more work to do, is very much appreciated

Eli will finish first.

Use 8/10 and 10/12. This represents how many spring rolls over how many minutes. Make your equations like this: 8/10 = 40/x and 10/12 = 40/x. Find x, which will give you the minutes it takes them to make 40 rolls.

You get x = 50 for the first one and x = 48 for the second. Nora makes 40 rolls  in 50 minutes, and Eli makes 40 rolls in 48 minutes. Eli is faster. 

Hope this helped! Please mark me brainliest!
