when the 69th even natural number is subtracted from the 119th odd natural number, what is the result

Answers

69th even number is: 69*2 = 138
119th odd number is: (2*119) - 1 = 237
69th even natural number subtracted from the 119th odd natural number is:
237 - 138 = 99.

Answer:

Step-by-step explanation:

The answer is 99 since you need to double 69 and also 119 and then subtract 1 from the double of 119. Then you would subtract them to get 99.

David invested $220 in a savings account that offers a 3% return on the investment. How many years will the value of David's investment will reach at least $400 ?

Answers

FV = PV ( 1 + i ) ^t
FV = $400, PV = $220, i = 3% = 0.03
400 = 220 * ( 1 + 0.03 ) ^t
( 1 + 0.03 ) ^t = 400 : 220 = 1.818181
t = log ( 1.03 ) 1.81818
t = 20
After 20 years his investment will reach at least $400.

Answer:

t=20
