A department store gives away a $10 gift card to every 20th customer and a $15 gift card to every 45th customer. Which customer will be the first to recieve both gift cards after this customer receives both gift cards what is the total amount in gift cards the store has given away

Idk idk idk idk idk idk

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%
