Step-by-step explanation:

The information about Katie's monthly salary is:

1. The gross monthly salary is $3800

2. The income taxes is 22% of her income

3. She saves 8% of her salary

We need to find how much Katie has to spend each month after taxes

and savings

∵ The income taxes is 22% of her income

∵ Her income is $3800

∴ The income taxes = $\frac{22}{100}$ × 3800

∴ The income taxes = $836

∴ The remaining of her salary after taxes = 3800 - 836

∴ The remaining of her salary after taxes = $2964

∵ She saves 8% of here salary

∵ Her salary after taxes = $2964

∴ Her savings = $\frac{8}{100}$ × 2964

∴ Her savings = $237.12

∴ The remaining of her salary after saving = 2964 - 237.12

∴ The remaining of her salary after saving = $2726.88

Katie has $2726.88 to spend each month after taxes and savings

Feliz [49]

Answer:

F is assigned the value of 15

$74AF_{16} = 29871_{10}$

Step-by-step explanation:

Hexadecimal number system is base 16 and it contain the following numbers:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

A has a value of 10

B has a value of 11

C has a value of 12

D has a value of 13

E has a value of 14

F has a value of 15

By completing the expanded notation:

$(7*4096) + (4*256) + (A * 16) + (F *1)\\= (7*4096) + (4*256) + (10 * 16) + (15 *1)\\= 28672 + 1024 + 160 + 15\\= 29871$

Huan deposited $850 into a college savings account earning 4.8% interest compounded annually. He also deposited $850 into a seco

Aliun [14]

Answer:

$508.41

Step-by-step explanation:

Compound interest is calculated with the formula:

$CI = P(1 + R)^T - P$

where P = Principal/ Initial amount = $850

R = Rate = 4.8% = 0.048

T = Time elapsed = 10 years

Hence, the compound interest is:

$CI = 850(1 +0.048)^{10} - 850\\\\\\CI = 850(1.048)^{10} - 850\\\\\\CI = (850 * 1.598) - 850\\\\\\CI = 1358.41 - 850\\\\\\$

CI = $508.41

The interest after the first 10 years is $508.41
