Rueben chews four pieces of gum a day. the gum is sold in packages of gum will he need to buy this week?

If he chews 4 pieces of gum a day that is 28 a week so if you need 28 and gum comes in packs of 7 28/7 is 4 so he will need 4 boxes of gum a week or 18 packs a month or 213 a year 

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
