Complete question :
You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.
A. Write an expression that represents the total number of quarters you take with you when you go shopping.
B. How much money do you have left?
Answer:
[20 + (0.4*20)] = 28 quarters
$3.5
Step-by-step explanation:
Given that:
Initial number of quarters = 20
Quarters in room = 40%
Hence, Numbe of quarters in room = 0.4 * 20 = 8
Total number of quarters taken for shopping :
(Initial amount + Numbe of quarters in room)
(20 + 8) = 28 quarters
50% of quarters was spent on shopping :
0.5 * 28 = 14 quarters
Total left :
28 - 14 = 14
Quarters left in dollars :
1 quarter = 25 cent = 0.25 dollars
14 * $0.25 = $3.5

Answer:
Step-by-step explanation:
Translating the phrase into an equation, we get:
And:
So the system of equations would be:
If you want to put it into slope-intercept form, you can simplify both equations:
W + 8 = -4 - 6w / + 6w;
7w + 8 = - 4 / -8;
7w = -12 /÷7
w = -12/7 is the solution of the equation.
We verify: -12/7 + 8 = -4 - 6 x ( -12/7 );
Then, -12/7 + 56/7 = -28/7 + 72/7;
44/7 = 44/7 ( TRUE );
