Can someone me solve this : at a store, 2 pillows and 3 pillow cases together cost $73.08. the total cost of 3 pillows and 4 sheets is $120.82. if the price of the pillows is 3 times as much as the price of a pillow case, what is the total cost of 5 pillows and 7 sheets?

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.
