Bella wants to buy a watermelon that costs 2.45 dollars. She also wants to buy candy for 1.39 dollars.

Raquel wanted to decorate his mansion for Halloween with a vast variety of frightening decorations. Raquel first took out some cotton pillow stuffing for fake spiderwebs. He randomly grabbed a fistful of the material, and weighed it. The stuffing weighed 1.39 ounces. Raquel then took a bigger clump, and then weighed that one. It was 2.45 ounces. Finally, he mashed them together and then weighed the resulting mass of webs. How many ounces was the total amount of webs Raquel was going to use for Halloween decorations?
The answer is 3.84 ounces.

I hope you like this answer, please Brainliest me, and have a wonderful day! :D

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
