Answer:
22
Step-by-step explanation:
The easiest way to do this is to multiply the number you got right by 1+ the percent you got wrong. In this case it would be 1+.18. If you multiply 18 by 1.18 you get 21.24. Because you cant have part of a question you need to round up. To check you can divide 18 by 22 and you get 81.81. I hope this helps!
Answer:
309
Step-by-step explanation:
The formula for simple interest is
A = P(1 + rt)
where A is the amount of money in the account
P is the principal invested
r is the interest rate in decimal form
t is the time invested in years
We know
P = 300
r = 4% = .04
t = 9 months = 9 months * 1 year/12 months = .75 year
Substituting into the equation
A = 300(1 + .04*.75)
=300 (1+.03)
=300(1.03)
= 309
