The sales tax rate is 5%. If Bernie buys a new basketball at $34, what will be the total cost including tax?
julsineya [31]

Answer:

$35.70

Step-by-step explanation:

5% would be 0.05 as a decimal.

multiply 34(0.05):

34(0.05)=1.7

This means that the sales tax would be $1.70.

Next, add $1.70+$34 to find the total cost

$1.70+$34=$35.70

This means that the total cost is $35.70

At age 25, you invest $1,500 that earns 8 percent each year. How much money will you have at age 65? $_____ (no comma) 32586.78
AysviL [449]

Answer:

The Money Invested At age 25 earns more because it earns more Interest As compare to The Money Invested At age 40.

Step-by-step explanation:

According To the Question,

  • Given, A Person Invested $1,500 at Age of 25, With an 8% Per Annum Interest Rate.

Thus, The Money He will have at age of 65 would be, $1,500 * (1.08)^{40} = 32586.78$ . Here The Interest Earn in 40 Year Is 31086.78$.

  • And, the Same Person Invested $1,500 at Age of 40, With an 11% Per Annum Interest rate.

Thus, The Money He will have at age of 65 would be, $1,500 * (1.11)^{25} = $20378.20 . Here The Interest Earn in 25 Years Is 18878.20$.

⇒ Now, it is understood that the same amount invested for different periods of time & with a different interest rate, Since The Amount who get more Interest Would earn More. hence, The Money Invested At age 25 earns more because it earns more Interest As compare to The Money Invested At age 40.
