Erica and Dana are collecting canned food to donate to a local charity. This morning, Dana had twice as many cans as Erica. Then Dana collected 8 more cans. If Dana has 42 cans of food. How many cans of food does Erica have? (Let e represent the number of cans of food Erica has).

its 42÷2= 21 i think

Step-by-step explanation:

because dana has twice the nb of cans erica has so it dana has 48 then erica has the half number

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
