The percentage is 6% cause, she said that the book was $50 but was original $56 , so ...first go by sabrinas cost ( 50 ) and the actual ( 56 ) so think how much was subtracted from the original price? s - 50 .. a- 56. .... 50 + 6 =56 so go by the amount of the price added to the percentage ...6 % is the answer..hoped this helped
45/50 and 46/50 could be one of the options of 4.5/5 and 4.6/5
<span>7e^(×/3)=14
</span><span>e^(×/3)=14/7
</span>e^(×/3)=2
take ln of both sides;
lne^(×/3)=ln2
****You should be familiar that lne^x=x as ln is the inverse function of e and vice versa****
then;
x/3=ln2
x=3ln2
x approximately is equal to 2.1
