In Richmond, Chloe ordered $40 worth of sushi. She knew that when the bill came, she would need to pay Richmond sales tax for 5% and would want to leave a 20% tip on the original $40. including tax and tip, How much did Chloe meal cost?

Answers

Answer:

$50

Step-by-step explanation:

Given data

Cost of sushi= $40

Tax= 5%

Tip= 20%

Let us find the amount of the tax and the tip

Tax

=5/100*40

=0.05*40

=$2

Tip

=20/100*40

=0.2*40

=$8

Hence the total amount paid is

=40+2+8

=$50

Answer:

$50

Step-by-step explanation:

To avoid confusion, we can solve for the sales tax and the tip separately.

Tip

Original Bill x 20%Original Bill x 1/5$40 x 1/5$8

Tax

Original Bill x 5%Original Bill x 1/20$40 x 1/20$2

Total

Original Bill + Tip + Tax$40 + $8 + $2$50

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?

Answers

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

To calculate the future value, we need to use the following formula:

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12
