1. find the balance after one year if you deposit all the money into an account that pays $2.50 in simple interest each month (this is a simple equation where the amount of interest stays the same each month).

2. Find the balance after one year if you deposit all the money into an account that pays 5% APR with monthly compounding.

If $600 is deposited into an account that pays $2.50 per month, the total amount after a year will be $630. If you instead deposited into an account earning 5%, the amount would be $630.70.

If you earn $2.50 per month, in a year you will earn:

= 2.50 x 12 months

= $30

Added to the original $600:

= 600 + 30

= $630

If the account makes 5% and is compounded monthly, you need to convert this rate to a monthly rate as well as the time period:

5% = 5/12 = 5/12% per month

1 year = 1 x 12 = 12 months

The amount after a year will be:

= Amount x ( 1 + rate) ^ number of periods

= 600 x ( 1 + 5/12%)¹²

= $630.70

In conclusion, you will have $630 using simple interest and $630.70 using monthly compounding.

1. Balance after 1 year with simple interest= 600 + (2.5 x 12) = 600 + 30 = $630

2. Balance after 1 year with compounded interest = P ( 1 +

= 600 ( 1 + = 600 (1.0511) = $630.66 = approx. $630

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
