Mr. hamm's salary has increased by 250% over the past 10 years. if his original salary was $28,000 per year, what is his current salary?

a) $35,000

b) $37,500

c) $70,000

d) $98,000

D) 98,000

Step-by-step explanation:

28000 + 2.5(28000) = 98000

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
