Answer:
Sheldon has to sell at least 143 cups of coffee to purchase the kayak.
Step-by-step explanation:
First write an expression:
15 + 0.25x ≥ 50.75
Next use inverse operations:
15 + 0.25x - 15 ≥ 50.75 - 15
0.25x ≥ 35.75
0.25x ÷ 0.25 ≥ 35.75 ÷ 0.25
x ≥ 143

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.
so we can just pick two random "x" values, hmmmmm say x = 0, what's "y"?
y = 7(0)-7 => y = -7....................................... so that gives us the point (0, -7)
hmmm x = 2, what is "y"?
y = 7(2) - 7 => y = 14-7 => y = 7................. so we get the point (2, 7).
then just plot those, and run a line through them.
