{ \tt{(4x + 1) + 2(x + 5) = 20}} \\ { \tt{4x + 1 + 2x + 10 = 20}} \\  { \tt{6x + 11 = 20}} \\ { \tt{6x = 20 - 11}} \\{ \tt{6x = 9}} \\{ \boxed { \tt{x =  \frac{3}{2} = 1.5 }}}

spencer took 21$ with him to the mall. At the music store, he spent 2/3 of his money on a DVD, he spent 1/4 of what he had left
Sunny_sXe [5.5K]

Answer:

$5.25 Dollars

Step-by-step explanation:

I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)

<em>Hope this helped! :)</em>
