Let the original profits be $x. 5% increase in profits will give us: 105/100×x=$1.05x 3% reduction in new profits ill give us the latest amount to be: 97/100×1.05x =$1.0185x comparing our new profits to our original amount of $x we shall have new percentage increase to be: (1.0185x-x)/x×100 =1.85% Thus our final increase 1.85%
After 1.4 seconds, t = 1.4. h(t) = 150 - 9(1.4) Multiply 9 by 1.4 to get 12.6. h(t) = 150 - 12.6 Subtract 12.6 from 150 to get 137.4. h(t) = 137.4. The height of the ball would be 137.4 after 1.4 seconds. Hope this helps!
