David looks into two brick companies to construct the brick border for his garden. Evergreen landscapers charges an installation fee of $250 plus $0.20 per brick. Garden Works charges an installation fee of $400 plus $0.05 per brick. For what amount of bricks do the two companies charge the same amount?

Respuesta :

Answer:

For 1,000 bricks, the amount charged will be the same

Step-by-step explanation:

Let the number of bricks for which they charge the same amount be $x

Thus;

The total cost from the first company will

be;

250 + 0.2(x) = 250 + 0.2x

The second will charge;

400 + 0.05(x) = 400 + 0.05x

Since the amount charged will be equal at x bricks, we need to equate both;

400 + 0.05x = 250 + 0.2x

400-250 = 0.2x-0.05x

150 = 0.15x

x = 150/0.15

x = 1,000
