Answer:I think it would be $9
Step-by-step explanation:
50% of 20 is $10
10% of $10 is $1
Subtract 1 from 10, which gives you $9
Let <em>q</em> be the number of quarts of pure antifreeze that needs to be added to get the desired solution.
8 quarts of 40% solution contains 0.40 × 8 = 3.2 quarts of antifreeze.
The new solution would have a total volume of 8 + <em>q</em> quarts, and it would contain a total amount of 3.2 + <em>q</em> quarts of antifreeze. You want to end up with a concentration of 60% antifreeze, which means
(3.2 + <em>q</em>) / (8 + <em>q</em>) = 0.60
Solve for <em>q</em> :
3.2 + <em>q</em> = 0.60 (8 + <em>q</em>)
3.2 + <em>q</em> = 4.8 + 0.6<em>q</em>
0.4<em>q</em> = 1.6
<em>q</em> = 4
Step-by-step explanation:
you would do 3 ÷ .99 and then when you get the answer from that you would multiply it by 5.
Well it would just be 54 since you just need to move the decimal over by 1.
So 5.4x10= 54
