The Sweet water High School Project Graduation committee is hosting a dinner-and-dance fundraiser at the Sweet water Community Center. The committee hopes to raise at least $7500 with this event. Tickets for the fundraiser are $75.00 per couple, and they have to pay a $375 fee for renting the community center. Write and solve an inequality to determine the minimum number of tickets they need to sell to reach their goal.

At least 105 tickets must be sold for there to be a 7500 dollar profit

Step-by-step explanation:

Let c = number of couple tickets

ticket sales - costs = profits

We want profits greater than 7500

75c - 375 ≥ 7500

Add 375 from each side

75c-375+375 ≥ 7500 +375

75c ≥ 7875

Divide each side by 75

75c/75 ≥ 7875/75

c ≥ 105

At least 105 tickets must be sold for there to be a 7500 dollar profit

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
