Acollege graduate expects to earn a salary of $55,000 during the first year after graduation and receive a 4% raise every year after that. what is the total income he will have received after ten years? a. $660,335.89 b. $582,053.74 c. $572,000.00 d. $741,749.33

Looks like your answers are incorrect. None of the answers are correct.

Lets examine:

In year 1, he or she earns 55,000 = 55,000 * (1.04)^0

In year 2, he or she earns

55,000*1.04 =

(55,000 * .04) + 55,000 =

55,000(1.04)^1

In year 3, he or she earns 55,000*(1.04)^2

In year 4, he or she earns 55,000*(1.04)^3

This continues to 55,000*(1.04)^9 = 78282.149 = 78282.15

Your answer should be 78,282.149 or or 78,282.14 or 78,282.15

answer: 1 + 1 = 11

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
