Enrique’s parents want to save for his education. on his 12th birthday, they deposit $6,000 in a savings account that pays 5% simple annual interest. what will the balance be when he turns 18?
a. $1,800
b. $3,000
c. $7,800
d. $9,800

C.

Step-by-step explanation:

Multiply 6,000 by .05, which is 5% in decimal form. This will come up as $300.

Since this is an annual rate, this is how much is added to the original $6,000 just for one year.

Meaning that he'll have 6,300 by the time he's 13, 6,600 when he's 14, and so on.

Add 300 to itself six times, the amount of years between his 12th birthday and his 18th birthday, and then add that to 6,000.

It should come up to be $7,800.

step-by-step explanation:

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
