Item 7 you spend $20 total on tubes of paint and disposable brushes for an art project. tubes of paint cost $4.00 each and paintbrushes cost $0.50 each. you purchase twice as many brushes as tubes of paint. how many brushes and tubes of paint do you purchase?

This was a trial and error question and since you have double the amount of brushes, you can start by trying random numbers. for the sake of time, i used 8brushes x $.50 to get $4 and 4tubes of paint x $4 to get $16 and $4+$16=$20 while also meeting the criteria.

Hey mate here is the answerthe correct answer is b may it will you
