What’s the answer to this?!!!

Need to increase the numbers of customers i talk to daily by 20% how many customers do i need to talk to if i talk to a average of 8 customers per hour during an 8 hour shift

(-y to the power of 2 - 4y- to the power of 2 -6 y +3)

Use the second shift theorem to find the inverse laplace transform of (e^−3s) / (s^2 + 2s − 3)
