Ben has a collection of baseball cards. He has a total of 1,600 cards. Of the baseball cards, 35% are dated before 1980, 25% are dated from 1980 to 2000, and
the rest are dated after 2000.
How many baseball cards in Ben's collection are dated after 2000?

Answers

Answer:

640 cards

Step-by-step explanation:

If the rest are dated after 2000, that means that 40% are dated after 2000, since 25% + 35% = 60%

To find how many are dated after 2000, multiply 1,600 by 0.4:

1,600(0.6) = 640

So, 640 of the baseball cards are dated after 2000

Josiah invested $96,000 in an account paying an interest rate of 3.5% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $153,400?

Answers

The number of years it will take for the value of the money in the account to reach $153,400 would be = 17 years.

What is simple interest?

Simple interest is defined as the amount of money that is received as an extra cash based on an investment made in an account.

The principal amount of money invested= $96,000

The rate of interest = 3.5%

The total interest on the principal amount = $153,400- $96,000 = $57,400

The time for this investment= ?

Using the formula for simple interest= p×T×R/100

57,400 = 96,000 ×T× 3.5 /100

Make T the subject of formula;

T = 57,400×100/96,000×3.5

T = 5740000/336000

T = 17 years (approximately)
