For this case we have:

Let x be the number of weeks you should work in the store. We have:

125x + 65 \geq 815

That is,125xrepresents the profit obtained according to the number of weeks worked.

65, represents the gain obtained in one night, in the store.

Cole's earnings must be greater than or equal to the cost of the trip and stay of the singing competition, so he can cover it.

Clearing x:

125x\geq 815-65\\ 125x\geq 750

x \geq\frac{750}{125}

x \geq6

Thus, the minimum number of weeks that Cole must work to cover the costs of the competition is 6.

Answer:

The minimum number of weeks is 6.

x \geq6

It would take 6 weeks for Cole to make 750$ and the 65$ he had received from the open mic would make it 815$
