Sarah had invested $800 in a savings account that paid 4.2% interest compounded annually. How much money was in the account afte
schepotkina [342]

Answer:  $943.11

<u>Step-by-step explanation:</u>

Compound Interest formula is:   A=P(1+r)^t     where

  • A is the Accrued amount (total earned)
  • P is the Principal (amount initially invested)
  • r is the interest Rate (convert percent to a decimal)
  • t is the Time (number of years)

It is given that; P = 800    r = 4.2% (0.042)       t = 4

A = 800(1 + 0.042)⁴

A = 800(1.042)⁴

A = 943.106   →   A = 943.11 (rounded to the nearest penny)

Sarah invested $800 for four years at an interest rate of 4.2% and accrued $943.11

Multiply the two mixed numbers 4 1/2 x 3 2/3 simplify your answer and write it as a mixed number
konstantin123 [22]

Answer: 16 1/2

Step-by-step explanation:

It's easiest to multiply improper fractions and then to convert them back into mixed numbers, so 4 1/2 would become 9/2 and 3 2/3 would become 11/3. \frac{9}{2} *\frac{11}{3}= 99/6. Now just simplify to 33/2 and then convert back into a mixed number.  16 1/2
