Anna spends $4.65 each weekday (20 weekdays/month) on coffee and buys a bag of coffee for $8.99 that lasts 6 months. Her monthly income is $2,350. What percent of her monthly income does she spend on coffee? 1) 0.58% 2)4.34% 3) 4.02% 4) 4.65%

C. 4.02%

Step-by-step explanation:

Anna spends $4.65 each weekday (20 weekdays/month) on coffee and buys a bag of coffee for $8.99 that lasts 6 months. Her monthly income is $2,350. What percent of her monthly income does she spend on coffee? 1) 0.58% 2)4.34% 3) 4.02% 4) 4.65%

She spends $4.65/weekday, and there are 20 weekdays/month

In 1 month, she spends:

$4.65/weekday * 20 weekdays/month = $93/month

In 6 months, she spends 6 * $93 = $558

She buys a bag of coffee for $8.99 that lasts 6 months.

The total cost of all coffee in 6 months is:

$558 + $8.99 = $566.99

Her income in 1 month is $2,350

Her income in 6 months is 6 * $2,350 = $14,100

The percent is:

566.99/14,100 * 100% = 4.02%

3) 4.02%

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.

step-by-step explanation:

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
