Answer:
Now, derive it from the calculations
Step-by-step explanation:
Net income = 100% = N120,000
therefore
1. Food
40%/100% = 2/5 of N120,000
= N48,000
2.Housing
30%/100% = 3/10 of N120,000
= N36,000
3. Savings
20%/100% = 2/10 (or 1/5) of N120,000
= N24,000
4. Miscellaneous
10%/100% = 1/10 of N120,000
= N 12,000

The statement is false because when you use distributive property, you get -12=-4+16 and when you add 16 to -4, you'll get 12, not -12, making the statement false.

So, she can make 2 batches of cupcakes.
175 mL at 25% concentration of alcohol contains 0.25 (175 mL) = 43.75 mL of alcohol. If <em>v</em> is the amount of the 70% solution that you use, then that amount contains 0.7<em>v</em> mL of alcohol.
Mixing these two yields a total volume of 175 mL + <em>v</em>, and it contains 43.75 mL + 0.7<em>v</em> alcohol. You want to end up with a concentration of 45%, which means the ratio of the amount of alcohol to the total volume needs to be 0.45:
(43.75 mL + 0.7<em>v</em>) / (175 mL + <em>v</em>) = 0.45
Solve for <em>v</em> :
43.75 mL + 0.7<em>v</em> = 0.45 (175 mL + <em>v</em>)
43.75 mL + 0.7<em>v</em> = 78.75 mL + 0.45<em>v</em>
0.25<em>v</em> = 35 mL
<em>v</em> = 140 mL
