Good evening ,

Answer:

Let p represent the percent​ then

P ≈ 38%

Step-by-step explanation:

2900+2900×(p÷100) = 4000

⇔ 2900×[1 + (p÷100)] = 4000

⇔ [1 + (p÷100)] = 4000÷2900

⇔ [(100÷100)+ (p÷100)] = 1.379310344828

⇔ 100+p = 100 × 1.379310344828

⇔ 100+p = 137.9310344828

⇔ p = 137.9310344828 - 100

⇔ p = 37.9310344828.
