The store bought a pair of shoes for 50.00 and sold it for 80.00 what percentage was the mark up?

60%

Step-by-step explanation:

The required markup percentage is 60%. The store bought the shoes for 50 dollars and got 30 dollars out of it when they sold it. And that mark up percentage is 60%. 30 dollars is 60 percent of the cost of the shoe. I don't know if you will understand this but this is the answer.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
