Hay dos máquinas que producen latas de aluminio. La máquina nueva produce 4200 latas en 210 minutos. La máquina más antigua produce la misma cantidad de latas en 280 minutos. Si las dos máquinas trabajan en conunto, cuánto tiempo les tomará producir 4200 latas?

I’m pretty sure the slope would be 1 since the x and y values increase by 1

Is there a picture because i cannot answer it sorry

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%
