Arianna bought 2 thingamajigs and 5 doohickies for $31. Samantha bought one thingamajig and 2 doohickies for $13. How much does a thingamajig cost?

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%

It is 6% because if you subtract 69-58=6 so 6% is the answer to your question.

Did you put in a negative answer? no matter if you + - ÷ or ×, it will be negative example: -21 ÷ 3 = -7
