A)The total cost would be: x=15a+12b+18c where x is the total cost and a,b,and c are the amount of stocks you bought from their respective companies.
B) Since you bought 10 A stocks, you must have bought 20 C stocks. That adds up to 30 bought, leaving 15 for B.
x=(15)(10)+(12)(15)+(18)(20)
x=150+180+360=$690 spent
C) A's stock is now 15(1.25) which is 18.75. C's stock is now 18(.90) which is 16.2
new equation is 18.75a+12b+16.2c=x
D) Substitute the number of stocks we bought from each in again:
187.5+180+324=$691.5
The cost went up slightly, so divide 690/691.5 then multiply that number by one hundred. You get that you spent in B 99.8% the amount you spent in C. So 100-99.8= an increase of <u>.2% </u>

Step-by-step explanation:
Since we're rounding to the hundredths place, we need to see if the thousandths place is greater or equal to 5. Since it is less than 5, we round down to 72.63.
Answer:
the percent error is 6.25%
Step-by-step explanation:
The computation of the percent error is shown below:
Percent error is
= (Experimental value - accepted value) ÷ (experimental value) × 100
= (80 degrees - 75 degrees) ÷ (80 degrees) × 100
= (5 degrees) ÷ (80 degrees) × 100
= 0.0625 × 100
= 6.25%
hence, the percent error is 6.25%
We simply applied the above formula so that the correct value could come
