marta [7]

Answer:

The answer is 16%

Step-by-step explanation:

use the percent error formula.

\frac{|E-T|}{|T|} *100

in this problem,

e= 75

t=90

substitute and solve.

\frac{|75-90|}{|90|} *100\\\frac{|-15|}{|90|}*100\\\\ .16667*100\\

16%

we are dealing with percents so rounding to nearest whole number will suffice.

hope this helps!

Cedro collects state quarters he has 42 out of 50 available quarters. What is 42 out of 50 as a percent?
FinnZ [79.3K]
The answer is 84%. This is because to get a percentage out of 100% you need to have 100 in your total so you multiply 50 *2 to get 100 and since you changed the 50 you also have to change your 42 by the same equation. So 42*2 is 84. Hope this helped please comment if you need clarifying.
