It costs $83 a day to rent a car plus a required fee for insurance. Suppose the total cost for renting the car for 7 days is $621. Write an equation to model this math situation. How much does the insurance cost? Which one is correct ?
a
581=621+b; b= -$40
b
621=83b+7; b= $7.41
c
621=83(7)+b; b= $40
d
621=83(7)+b; b= $1

C

Step-by-step explanation:

83 * 7 = 581, 621 - 581 = 40, $40 is the fee for insurance

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.
